12.24 Air flows isentropically through a converging nozzle attached to a large tank, where the absolute pressure is 171 kPa and the temperature is 27 C. At the inlet section the Mach number is 0.2.

The nozzle discharges to the atmosphere; the discharge area is 0 015 m2. Determine the magnitude and direction of the force that must be applied to hold the nozzle in place.
