Question

1.       Air flows through a horizontal conical nozzle, discharging to atmosphere.  The nozzle inlet diameter is 30 cm and the outlet diameter is 15 cm.  If an exit velocity of 40 m/s is desired determine the gage pressure of the air at the inlet of the nozzle.  Assume steady, incompressible, uniform flow.

Please explain in detail if possible. Thank you.
