A turbojet aircraft flies with a velocity of 1100 km/h at an altitude where the air temperature and pressure are -35°C and 40 kPa. Air leaves the diffuser at 50 kPa with a velocity of 15 m/s, and combustion gases enter the turbine at 450 kPa and 950°C. The turbine produces 800 kW of power, all of which is used to drive the compressor. Assuming an isentropic efficiency of 83 percent for the compressor, turbine, and nozzle, and using variable specific heats, determine
(a) the pressure of combustion gases at the turbine exit,
(b) the mass flow rate of air through the compressor,
(c) the velocity of the gases at the nozzle exit, and
(d) the propulsive power and the propulsive efficiency for this engine.
Consider a simple ideal Brayton cycle operating between the temperature limits of 300 and 1500 K. Using constant specific heats at room temperature, determine the pressure r
Determine the mass flow rates at the two outlets (flue gas and fly ash) when 10 kg/s of flue gas and ash mixture enters this unit. Also determine the amount of fly ash colle
A steady-flow compressor is used to compress helium from 15 psia and 70°F at the inlet to 200 psia and 6008F at the outlet. The outlet area and velocity are 0.01 ft2 and 100
The ventilating fan of the bathroom of a building has a volume flow rate of 30 L/s and runs continuously. If the density of air inside is 1.20 kg/m3 , determine the mass of
Air whose density is 0.078 lbm/ft3 enters the duct of an air-conditioning system at a volume flow rate of 450 ft3 /min. If the diameter of the duct is 10 in, determine the v
A house is maintained at 1 atm and 24°C, and warm air inside a house is forced to leave the house at a rate of 150 m3 /h as a result of outdoor air at 5°C infiltrating into
The stators in a gas turbine are designed to increase the kinetic energy of the gas passing through them adiabatically. Air enters a set of these nozzles at 300 psia and 700
Determine the velocity of the water at the inlet and outlet when the mass flow rate through the pump is 0.5 kg/s. Will these velocities change significantly if the inlet tem
