Air enters a constant area combustion chamber at 100 m/s and 400 K. Determine the exit conditions if the heat added is (a) 1000 kJ/kg and (b) 2000 kJ/kg. Also determine the ratio of mass flow rates between the two cases. Assume that the inlet stagnation conditions remain the same for the two cases .

A two-part compressor operates with steady state conditions. The exit of the first part of the compressor is also the inlet of the second part of the compressor. In the first part of the compressor, air is compressed from 1.5 bar, 350 K to 5.5 bar with a mass flow rate of 7.2 kg/sec. In the second part of the compressor, air is compressed from 5.5 bar to 9.5 bar with a mass flow rate of 5.8 kg/sec. Each unit...

1) A nozzle is a device for increasing the velocity of a steadily flowing stream of fluid. At the inlet to a certain nozzle the enthalpy of the fluid is 3025 kJ/kg and the velocity is 60 m/s. At the exit from the nozzle the enthalpy is 2790 kJ/kg. The nozzle is horizontal and there is negligible heat loss from it. (i) Find the velocity at the nozzle exit. (ii) If the inlet area is 0.1 m2 and specific volume...

Assume that air is drawn steadily through a frictionless, adiabatic converging‐diverging nozzle into a frictionless, constant‐area duct with heat addition. The air enters the constant area pipe section at a static pressure of 200 kPa, static temperature of 500K, and velocity of 400 m/s. (a) If 500 kJ/kg is removed from the flow, determine the static pressure, static temperature and velocity of the flow leaving the duct. (b) What is the maximum amount of heat addition for these inflow conditions?...

A fuel gas consists of 75% butane (C4H10), 10% propane (C3H8) and 15% butene (C4H8) by volume. It is to be fed to the combustion chamber in 10% excess air at 25ºC, where it is completely burnt to carbon dioxide and water. The flue gases produced are to be used to generate 5 bar steam from water at 90ºC. (a) Write balanced equations for the combustion of each component of the fuel gas. (b) Explain the need for excess air....
