A high-pressure washing system's pump supplies 1 gallon of water per second at 100 psi pressure. The nozzle should be designed so that the static pressure of the water as it exits the nozzle is the same as the atmospheric pressure. If the inside diameter of the hose leading from the pump to the nozzle is 2 in., what should the diameter of the nozzle exit be? What will be the velocity of the water at the exit of the nozzle?
