Air contained within a piston cylinder assembly undergoes three processes in series:
Air contained within a piston-cylinder assembly is slowly heated. As shown in Fig. during this process the pressure first varies linearly with volume
Air enters a 28-cm diameter pipe steadily at 200 kPa and 20°C with a velocity of 5 m/s. Air is heated as it flows, and leaves the pipe at 180 kPa and 40°C
Air enters a 30-cm-diameter cooling section at 1 atm, 35°C, and 60 percent relative humidity at 120 m/min.
Air at 8 psia, 20°F, and a Mach number of 2.0 is forced to turn upward by a ramp that makes an 8° angle off the flow direction
Air at 80 kPa and 127°C enters an adiabatic diffuser steadily at a rate of 6000 kg/h and leaves at 100 kPa.
Air at 80 kPa, 27°C, and 220 m/s enters a diffuser at a rate of 2.5 kg/s and leaves at 42°C. The exit area of the diffuser is 400 cm2
Air at 800 kPa and 400°C enters a steady-flow nozzle with a low velocity and leaves at 100 kPa. If the air undergoes an adiabatic expansion process
Find the power delivered to the piston. You should solve the problem in a step by step.You must include all the units which are needed
Air at 30 psia, 212°F, and Mach number Ma = 0.8 flows through a duct. Calculate the velocity and the stagnation pressure, temperature, and density of air.
Air at 300 K is flowing in a duct at a velocity of
Air at 327°C, 400 kPa with a volume flow 1 m3/s runs through an adiabatic turbine with exhaust pressure of 100 kPa
Air at 500 K, 500 kPa is expanded to 100 kPa in two steady flow cases. Case one is a throttle and case two is a turbine. Which has the highest exit T?
Air at 7°C enters a turbojet engine at a rate of 16 kg/s and at a velocity of 300 m/s (relative to the engine)
Acetylene (C2H2) is burned with stoichiometric amount of air during a combustion process. Assuming complete combustion, determine the air-fuel ratio on a mass
Acetylene gas at 25?C is burned with 140% theoretical air, which enters the burner at 25?C, 100 kPa, 80% relative humidity
Acetylene gas (C2H2) is burned completely during a steady-flow combustion process. The fuel and the air enter the combustion chamber at 25°C
Acetylene gas (C2H2) at 25°C is burned during a steady-flow combustion process with 30 percent excess air at 27°C
Air at 1 atm, 15°C, and 60 percent relative humidity is first heated to 20°C in a heating section and then humidified by introducing water vapor.
Air (assumed to be 79% nitrogen and 21% oxygen) is heated in an SSSF process at a constant pressure of 14.7 lbf/in 2, and some NO is formed
Air (21 percent O2, 79 percent N2) is heated to 5400 R at a pressure of 1 atm. Determine the equilibrium composition, assuming that only O2, N2
