Water flows through a hose with a diameter of 3.0 cm at a rate of 1.0 L/s. Phho
= 1,000 kg/m³.
The hose is lifted 1.5 m above the ground.
a) How will this change in height affect the pressure and velocity of the water? Explain.
b) At the end of this hose is a nozzle with a diameter of 1.5 cm. Calculate the velocity of the water as it
leaves the nozzle.
c) The nozzle is connected to a small circular valve with a diameter of 1.5 cm which is part of a large
tank filled with water. At the other end of this tank is a large piston which has a diameter of 15.0 cm.
Determine the ratio of the force due to the water leaving the nozzle and the force acting on the piston.
