Answer:

Electric current is the movement of electrons through a wire. Electric current is measured in amperes (amps) and refers to the number of charges that move through the wire per second. If we want current to flow directly from one point to another, we should use a wire that has as little resistance as possible.Current is directly proportional to voltage, inversely proportional to resistance. One of the most common electrical measurements you'll use is the watt, a unit of electrical power: W (Watts) = E (Volts) x I (Amperes). The quantity of electric charge is measured in coulombs.They can even pass through bones and teeth. This makes gamma rays very dangerous. They can destroy living cells, produce gene mutations, and cause cancer.

Answer:

The answer is below

Explanation:

Both a gage and a manometer are attached to a gas tank to measure its pressure. If the reading on the pressure gage is 65 kPa, determine the distance between the two fluid levels of the manometer if the fluid is a) mercury b) water

Solution:

A manometer is a device used to measure pressure. A manometer is made up of a U shaped tube containing liquid. The difference of pressure in the two arms causes the liquid to reach different heights.

a) The density of mercury ([tex]\rho_{Hg}[/tex]) = 13600 kg/m³, Pressure (P) = 65 kPa and g = 9.8 m/s², h = distance between the two fluid levels

[tex]P=\rho_{Hg}*g*h\\\\h=\frac{P}{\rho_{Hg}*g} =\frac{65*10^3\ Pa}{13600*9.81}=0.487\ m[/tex]

b) For water, [tex]\rho_w[/tex] = 1000 kg/m³, hence:

[tex]P=\rho_{w}*g*h\\\\h=\frac{P}{\rho_{w}*g} =\frac{65*10^3\ Pa}{1000*9.81}=6.6\ m[/tex]

$255 per hour

Total number of employed people = 16

(i) 5 people earn $15 per hour

That means that the total amount earned by those 5 is;

5 x $15 = $75 per hour

(ii) 4 people earn $17 per hour

That means that the total amount earned by those 4 is;

4 x $17 = $68 per hour

(iii) The remaining people earn $16 per hour.

There are 7 people remaining. i.e

16 - 5 - 4 = 7

That means that the total amount earned by those remaining (7) is;

7 x $16 = $112 per hour

The total hourly wage is therefore the sum of all the results in i, ii and iii. i.e

Total = $75 + $68 + $112

Total = $255

Therefore, the total hourly wage earned by all 16 people is $255

Answer:

b) 1235.6 °F.

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to set up an energy balance for the turbine's inlets and outlets:

[tex]m_{in}h_{in}=W_{out}+m_{out}h_{out}[/tex]

Whereas the mass flow is just the same, which means we have:

[tex]W_{out}=m_{out}(h_{out}-h_{in})[/tex]

And the enthalpy and entropy of the inlet stream is obtained from steam tables:

[tex]h_{in}=1860.7BTU/lbm\\\\s_{in}= 2.2096BTU/lbm-R[/tex]

Now, since we assume the 80% accounts for the isentropic efficiency for this adiabatic gas turbine, we assume the entropy is constant so that:

[tex]s_{out}= 2.2096BTU/lbm-R[/tex]

Which means we can find the temperature at which this entropy is exhibited at 15 psia, which gives values of temperature of 1200 °F (s=2.1986 BTU/lbm-K) and 1400 °F (s=2.2604 BTU/lbm-K), and thus, we interpolate for s=2.2096 to obtain a temperature of 1235.6 °F.

Moreover, the enthalpy at the turbine's outlet can be also interpolated by knowing that at 1200 °F h=1639.8 BTU/lbm and at 1400 °F h=174.5 BTU/lbm, to obtain:

[tex]h_{out}=1659.15BUT/lbm[/tex]

Then, the isentropic work (negative due to convention) is:

[tex]W_{out}=2500lbm/h(1659.15BUT/lbm-1860.7BUT/lbm)\\\\W_{out}=-503,875BTU[/tex]

And the real produced work is:

[tex]W_{real}=0.8*-503875BTU\\\\W_{real}=-403100BTU[/tex]

Finally, in horsepower:

[tex]W_{real}=-403100BTU/hr*\frac{1HP}{2544.4336BTU/hr} \\\\W_{real}=158.4HP[/tex]

Answer:

the energy is sgdrh35679

Answer:

the minimum power input required for this air-conditioning system is 1.20 hp

Explanation:

Given the data in the question;

Temperature inside ( Sink ) T[tex]_L[/tex] = 70°F = ( 70 + 460 )R = 530 R

temperature outside ( source )T[tex]_H[/tex] = 100°F = ( 100 + 460 )R = 560 R

[tex]Q_W[/tex] = 800 Btu/min

[tex]Q_L[/tex] = 100  Btu/min

Now, from the equation of coefficient of performance of refrigerator;

[tex]COP_{Ref[/tex] = Desired output / Required input

[tex]COP_{Ref[/tex] = [tex]Q_{out[/tex] / [tex]W_{net[/tex] --------- let this be equation 1

[tex]COP_{Ref[/tex] = ( [tex]Q_L + Q_W[/tex] ) / [tex]W_{net[/tex]

where [tex]Q_W[/tex] is the rate heat gained through the wall

[tex]Q_L[/tex] is the heat generation from people and lights and appliances.

Now, lets consider the equation coefficient of performance of refrigerator in terms of temperatures;

[tex]COP_{Ref[/tex] = [tex]T_L[/tex] / ( [tex]T_H[/tex] - [tex]T_L[/tex] )

we substitute

[tex]COP_{Ref[/tex] = 530 / ( 560 - 530 )

[tex]COP_{Ref[/tex] = 530 / 30

[tex]COP_{Ref[/tex] = 17.667

so we substitute into equation 1;

[tex]COP_{Ref[/tex] = [tex]Q_{out[/tex] / [tex]W_{net[/tex] ---------

[tex]COP_{Ref[/tex] = ( [tex]Q_L + Q_W[/tex] ) / [tex]W_{net[/tex]

17.667 = ( 100 + 800 ) / [tex]W_{net[/tex]

17.667 = 900 / [tex]W_{net[/tex]

[tex]W_{net[/tex] = 900 / 17.667

[tex]W_{net[/tex] = 50.94 Btu/min

[tex]W_{net[/tex] = ( 50.94 / 42.53 ) hp

[tex]W_{net[/tex] = 1.198 hp ≈ 1.20 hp

Therefore, the minimum power input required for this air-conditioning system is 1.20 hp

Answer:

The correct answer is "1341.288 W/m".

Explanation:

Given that:

T₁ = 300 K

T₂ = 500 K

Diameter,

d = 0.2 m

Length,

l = 1 m

As we know,

The shape factor will be:

⇒ [tex]SF=\frac{2 \pi l}{ln[\frac{1.08 b }{d} ]}[/tex]

By putting the value, we get

⇒       [tex]=\frac{2 \pi l}{ln[\frac{1.08\times 1}{0.2} ]}[/tex]

⇒       [tex]=3.7258 \ l[/tex]

hence,

The heat loss will be:

⇒ [tex]Q=SF\times K(T_2-T_1)[/tex]

       [tex]=3.7258\times 1\times 1.8\times (500-300)[/tex]

       [tex]=3.7258\times 1.8\times (200)[/tex]

       [tex]=1341.288 \ W/m[/tex]

Answer:

The outer diameter of the spacers that yields the most economical and safe design is 25.03 mm

Explanation:

For steel bolt

Stress = 210 MPa or 210 N/mm2

Pressure = Stress* Area

Pbolt = 210 N/mm2 * 16^2 *(pi)/4

Pbolt = 210 N/mm2 * 200.96 mm^2 = 42201.6  N

For Brass spacer

Pressure = 42201.6  N

Area of Brass spacer = Pressure/Stress

Area of Brass spacer = 42201.6  N/145 N/mm^2 = 291.044 mm^2

Area of Brass spacer = (pi) (d^2 - 16^2)/4 =  291.044 mm^2

d^2 - 16^2 = 291.044 mm^2* 4/(pi) = 370.758

d^2 =  370.758 + 16^2

d^2 =   626.758

d = 25.03 mm

The outer diameter of the spacers that yields the most economical and safe design is 25.03 mm

Answer:

C. Low viscosity for Maine in the winter and high viscosity for Florida in the summer.

Explanation:

The choice of motor oil or engine oil depends on the type of engine and also on the type of climate on which the engine runs.

In winter climates, we should use oil with low viscosity as at lower temperatures, the it flows more readily if its viscosity is low.

But the summer season needs a relatively thicker oil so as to reduce the thinning effect of the oil out of the engine.

Thus for Maine in the winter season, we need a low viscosity oil and for Florida a high viscosity oil in the summer season.

Therefore, option (c) is correct.

Answer:

The following description of the problem is provided.

Explanation:

Answer:

a) 156 meters

b) 58 m/s

c) 9.8 m/s^2

Explanation:

a) The horizontal displacement X = V *t

X = 50 * 3 = 150 meters

Vertical displacement = y = – g * t² / 2

Y = -9.8 *3*3/2 = -4.9*9 = 44.1

Net Displacement = Sqrt (X^2 +Y^2) = 156.34 = 156 meters

b) Speed of the projectile

vx = 50 m/s

vy = t*g = 9.8*3 = 29.4

V = Sqrt (vx^2 + vy^2) = 58 m/s

c) Acceleration is the acceleration due to gravity = 9.8 m/s^2

The magnitude of the displacement of the projectile is equal to 156 meters.

Given the following data:

Scientific data:

Mathematically, the magnitude of the displacement of a projectile is given by this formula:

[tex]Horizontal\;displacement = Vt\\\\Horizontal\;displacement = 50.0 \times 3.00[/tex]

Horizontal displacement = 150.0 meters.

[tex]Vertical displacement =\frac{1}{2} gt^2\\\\Vertical displacement =\frac{1}{2} \times 9.8 \times 3^2\\\\Vertical displacement =\frac{1}{2} \times 9.8 \times 9[/tex]

Vertical displacement = 44.1 meters.

[tex]D^2 = X^2 +Y^2\\\\D =\sqrt{44.1^2+150^2}[/tex]

D = 156.34 ≈ 156 meters.

b. For the speed of the projectile:

Vertical speed = tg

[tex]V_y = tg = 9.8\times3\\\\ V_y = 29.4\;m/s[/tex]

[tex]D^2 = V_x^2 +V_y^2\\\\D =\sqrt{50^2+29.4^2}[/tex]

D = 58 m/s.

c) The magnitude of the acceleration of the projectile is equal to the acceleration due to gravity ([tex]9.8 \;m/s^2[/tex]).

Answer:

All of the above

Explanation:

firstly, a creep can be explained as the gradual deformation of a material over a time period. This occurs at a fixed load with the temperature the same or more than the recrystallization temperature.

Once the material gets loaded, the instantaneous creep would start off and it is close to electric strain. in the primary creep area, the rate of the strain falls as the material hardens. in the secondary area, a balance between the hardening and recrystallization occurs. The material would get to be fractured hen recrstallization happens.  As temperature is raised the recrystallization gets to be more.
