A nozzle is attached to the end of a garden hose to increase the exit velocity of the water. Consider a hose with inside diameter of 5/8 in. and a nozzle with exit diameter 1/3 of its entrance diameter. Determine the pressure [psia] at the hose inlet if the volumetric flow rate is 3.5 gpm. Assume steady, incompressible, frictionless flow. The ambient pressure is 14.7 psia.
