1. Measurements on a prototype nozzle using air produce inlet and exit temperatures of 70.0°F and 60.0°F, respectively, while the exit velocity is 325 ft/s. Determine the nozzle's efficiency and velocity coefficient.

2. An air diffuser has inlet and exit isentropic stagnation pressures of 3.50 and 3.10 MPa, respectively. The inlet velocity is 300. m/s and the inlet static temperature is 27.0°C. Determine the diffuser efficiency, pressure recovery coefficient, and exit static temperature, if the air leaves the diffuser with a negligible velocity.
