Acombined gas-steam power cycle uses a simple gas turbine for the topping cycle and a simple rankine cycle for the bottoming cycle. atmospheric air enters the compressor at 101 kpa and 20 degc, and the maximum gas cycle temperature is 1100 degc. the compressor pressure ratio is 8; the compressor isentropic efficiency is 85 percent; and the gas turbine isentropic efficiency is 90 percent. the gas stream leaves the heat exchanger at the saturation temperature of the steam flowing through the heat exchanger. steam flows through the heat exchanger with a pressure of 6000 kpa and leaves at 320 degc. the steam cycle condenser operates at 20 kpa, and the isentropic efficiency of the steam turbine is 90 percent. determine the mass flow rate of the air through the air compressor required for this system to produce 100 mw of power. use constant specific heats for air at room temperature. ( 279 kg/s).

Samir watches a 100-minute movie on his spaceship. maria's spaceshipe flies in the same direction as samir's spaceship but she observes his move to last 125 minutes and his spaceship to be 40 m long. how long does samir observe his own spaceship to be? according to an observer on earth, planet x is stationary. maria and samir depart earth on their spaceships at the same time, each flying at 0.5c. maria flies toward planet x and samir flies in the opposite direction. according to maria, her voyage to planet x takes 9 years. how many years does marias voyage take according to samir?
