Water flows at 0.60 m/s through a 3.0 cm diameter hose that terminates in a 0.25 cm diameter nozzle. Assume laminar non-viscous steady-state flow.
(a) At what speed does the water pass through through the nozzle?
(b) If the pump at one end of the hose and the nozzle at the other end are at the same height, and if the pressure at the nozzle is 1 atm, what is the pressure at the pump?
atm
