A fire truck has its hose connected to a hydrant where the pressure is 7x10^4 Pa gage. The hose then connects up to a pump run by the engine of the fire truck. From here there extends hose to a fire fighter who, while crouching, is aiming the water at a 60 degree angle with the ground to enter a window on the third floor 13 m above the nozzle at the end of the hose. As the water goes through the window, it is moving parallel to the ground. The total length of the hose is 65 m with 200-mm diameter. The exit diameter of the nozzle is 100 mm. Take e/D for the hose as 0.0001. What power is needed from the pump on the water? Take the nozzle exit to have the same elevation as the hydrant outlet. Neglect minor losses. Take the kinematic velocity to be 0.113x10^-5 m^2/s.
