The drinking fountain outside your classroom shoots water about 16.6 cm up in the air from a nozzle of diameter 0.594 cm. The pump at the base of the unit (1.20 m below the nozzle) pushes water into a 1.20 cm diameter supply pipe that goes up to the nozzle. What gauge pressure does the pump have to provide? Ignore the viscosity; your answer will therefore be an underestimate.
This solution measures the gauge pressure a pump must provide to push water into a 1.20 cm diameter pipe and shoot 16.6 cm in the air.
