Consider the nozzle given below. The nozzle exit has an area
0.0011 m^2 and a pressure of 0 kPa (gauge). Given the mass flow and
cross sectional area of the nozzle entrance, what is the pressure
at the nozzle entrance (P1) ? Give the answer in kPa gauge, but do
not enter the units in the answer box. The fluid is water with a
density of 1000 kg/m^3. Ignore work and friction. The external
force is still unknown.
