3. Water towers are often used to maintain city water pressure. In many locations, the static pressure is 65 psi. Calculate the height of liquid in a water tower that is necessary to maintain this pressure.

Water entering through 5 ft long and 1 inch diameter pipe has a flow rate of 100 kg/min at a temperature of 100°C and pressure of 2 bar. The density of water at these conditions is 961.5 kg/m3. Calculate the rate of work done at the entrance of pipe.

a) Water discharges at a rate of 5L/s through a nozzle. The jet, 25 mm in diameter, strikes a flat plate held perpendicular to its line of flow. Determine the magnitude of the force on the plate.
