Answer:
The reason is because when the wind approaches each sailboat from a different side, the sailboat that the wind approaches from the port side, which is the left side is the give-way vessel.
Whereby the wind approaches the vessel A from the port (left) side then vessel A is considered the give-way vessel
The give-way vessel is the vessel that will have to take expeditious steps to create access for the other vessels by either changing course, stopping, or moving with reduced speed

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.
You should continuously work to enhance your skills and knowledge .
Answer:
Improve Your Writing
You may need to improve your ability to express yourself in writing.
To some degree, most organisations rely on the accurate transfer of information and that calls for the accurate use of language. When speaking, most people make multiple errors of grammar and vocabulary, and nobody seems to mind. But when you are doing business at work, then the business agreement is usually in the form of a written document; and that document has to be worded properly.
How would you rate your ability to express yourself properly in writing? Are you a good writer or do you lack knowledge of grammar, punctuation, logic and rhetoric?
If you are not as good at writing as you need to be, then study grammar, study punctuation, logic and rhetoric.
Start by buying a copy of a book called 'Rex Barks' by Phyllis Davenport.
This book is the gateway to grammar - and Phyllis is phenomenal.

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. :)
how many types of engineering specialist are there?
There are now six major branches of engineering: Mechanical, Chemical, Civil, Electrical, Management, and Geotechnical, and literally hundreds of different subcategories of engineering under each branch.
There are about 40 types of engineering specialists
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
