Steam enters an adiabatic turbine at 8 MPa and 500 C with a mass flow rate of 3 kg/s andleaves at 30 kPa.The isentropic efficiency of the turbine is 0.90. Neglecting the kinetic energy change of the steam, determine (a) the tem-perature at the turbine exit and (b) the power output of theturbine
Answer:
(a) The exit temperature = 69.1°C
(b) The power output = 8.3 MW
Explanation:
(a) The enthalpy of steam at 8 MPa and 500°C is given (from online sources) as h₁ = 3399 kJ/kg
The exit temperature = The saturation temperature at 30 kPa = T₄ = 69.096 + 273.15 = 342.246 K
The exit temperature = 69.1°C
(b) The mass flow rate = 3 kg/s
The isentropic efficiency = 0.9 = (h₁ - h₂)/(h₁ - h₂[tex]_s[/tex])
s₁ = 6.727 kJ/kgK
h₂[tex]_s[/tex] = 289.229+ 2335.32* (6.8235 - 6.727 )/6.8235 = 322.26 kJ/kg
Therefore, h₂ = h₁ - (h₁ - h₂[tex]_s[/tex])*0.9
h₂ = 3399 - (3399 - 322.26 )*0.9 = 629.934 kJ/kg
The power output = [tex]\dot m[/tex](h₁ - h₂) = 3 *(3399 - 629.934) = 8307.2 kJ/s =
8.3 MW.
Question 6: Which of the following is NOT true if you are changing into a
turning lane?
You should activate your signals 100 feet beforehand
You should activate your signals when you get into the turn lane
You should activate your signals before you get into the turn lane
You should use your hands to signal if your lights do not work
Answer:
You should activate your signals 100 feet before you turn, becuase of that you should not wait until you are turning to turn on your signals. If you do not have working lights use your hands. So the answer that is inccorect is B.
You should activate your signals when you get into the turn lane is NOT true
Because you are supposed to single beforhand not while you're in the lane.
Im taking my drivers ed too. :)
A ____ is marked by two sets of double yellow lines, with each set having a broken line on the inside, and a solid line on the outside. white arrows appear in this lane as well.
Answer:
center left-turn lane
Explanation:
A center left turn lane will be marked as described. The arrows, if present, generally indicate that left turns are permitted from the lane with these markings.
__
If the double yellow lines are solid, they are considered to be a "barrier" and are not to be crossed.
Answer:
center left-turn lane
Explanation:
Prescription eye protection suitable for an electrician should always include a. a safety strap b. soft nose guards c. side shields d. tinted lenses
Answer:
The correct option is;
Side shields
Explanation:
Electricians working at a construction site are exposed to arc flashes and sparks which can enter into the eyes causing painful sensation as such a prescription eye protection suitable for an electrician according to OSHA regulations the employer should ensure that the electrician makes use of eye protection that has side protection in situations that include hazards from flying objects.
