Air enters a combustion chamber at a mach number of 3.5 with a pressure and temperature of 120 kpa and 400 C. the mach number at the exit is 1.2. find the amount of heat per unit mass added to the flow. What are the pressure and temperature at the exit of the combustor?
Air flows through a constant area duct. The pressure and temperature of the air at the inlet to the duct are P1 = 100 kPa absolute, and T1 = 298 K, respectively. Inlet Mach number is M1 = 0.1. Heat is transferred to the air as it flows through the duct and as a result the Mach number at the exit increases. a) Find the pressure and temperature at the exit, while the exit Mach number changes between M=0.2 to...

Air with a stagnation pressure of 1000 kPa and stagnation temperature of 500 K flows isentropically into a 100 kPA ambient (back) pressure. Calculate the Area ratio at the exit of a nozzle for isentropic flow with these conditions. Further if flow is considered isentropic within the nozzle calculate the isentropic nozzle efficiency if the area ratio at the nozzle exit were 1.2 rather than your calculated value for isentropic exit conditions above.
