Ajet engine is being tested on a test stand. the inlet area to the compressor is 0.2 m2 and air enters the compressor at 90 kpa, 100 m/s. the pressure of the atmosphere is 100 kpa. the exit area of the engine is 0.1 m2, and the products of combustion leave the exit at a pressure of 130 kpa and a temperature of 1000 k. the air fuel ratio is 46 kgair/kgfuel , and the fuel enters with a low velocity. the mass flow rate of air entering the engine is 20 kg/s a)determine the inlet temperature b) determine the exit velocity of combustion products. c) determine the thrust on the engine

Use henry's law and the solubilities given below to calculate the total volume of nitrogen and oxygen gas that should bubble out of 1.7 l of water upon warming from 25 ˚c to 50 ˚c. assume that the water is initially saturated with nitrogen and oxygen gas at 25 ˚c and a total pressure of 1.0 atm. assume that the gas bubbles out at a temperature of 50 ˚c. the solubility of oxygen gas at 50 ˚c is 27.8 mg/l at an oxygen pressure of 1.00 atm. the solubility of nitrogen gas at 50 ˚c is 14.6 mg/l at a nitrogen pressure of 1.00 atm. assume that the air above the water contains an oxygen partial pressure of 0.21 atm and a nitrogen partial pressure of 0.78 atm.
