Air enters the compressor of a gas-turbine plant at ambient conditions of 100 kpa and 25°c with a low velocity and exits at 1 mpa and 347°c with a velocity of 90 m/s. the compressor is cooled at a rate of 1500 kj/min, and the power input to the compressor is 260 kw. determine the mass flow rate of air through the compressor. (round the final answer to the nearest three decimal places.)

Imagine you are riding on a yacht in the ocean and traveling at 20 mph. you then hit a golf ball at 100 mph from the deck of the yacht. you see the ball move away from you at 100mph, while a person standing on a near by beach would observe your golf ball traveling at 120 mph (20 mph + 100 mph). now imagine you are aboard the hermes spacecraft traveling at 0.1c (1/10 the speed of light) past mars and shine a laser from the front of the ship. you would see the light traveling at c (the speed of light) away from your ship. according to einstein’s special relativity, how fast will a person on mars observe the light to be traveling? a) 0.1c (1/10 the speed of light) b) c (the speed of light) c)1.1c (c+0.1c)
