A diffuser is a steady-state device in which a fluid flowing at high velocity is decelerated. What are the exit pressure and temperature of the air?
Determine the exit pressure and cross-sectional area of the nozzle if the mass flow rate is 0.15 kg/s and the expansion is reversible and adiabatic.
Steam enters a turbine at 3 MPa, 450oC and expands in a reversible adiabatic process. What is the mass flow rate of steam through the turbine?
To increase the work out of a turbine for given inlet and exit pressures, how should the inlet state be changed?
