Unformatted text preview: SP20: Air passing through a gas turbine, heat exchanger, and nozzle is shown below. Air exiting the turbine stage is heated inside a heat exchanger using another stream of air. The velocity of air exiting the heat exchanger and entering the nozzle is negligibly small. The pressures and temperatures of air at various points in the system are indicated below. , air main m , . air HEX m kg 18 9 s turbine W 10 MW , air main m (a) Calculate the mass flow rate of air (kg/s) in the main stream i.e. passing through the turbine-heat exchanger-nozzle. (b) What is the temperature (K) of air at the nozzle inlet? (c) Determine the velocity (m/s) of air at the nozzle exit....
