1. Water is pumped from closed reservoir at a flow rate Q m/s through a 3 m pipe with an inside diameter of 0.225 m, using a centrifugal pump. The pump is located 2 m distance below the water level in the first closed tank and 15 m distance below the water level in the second tank. The pressure gauge readings for the first and the second tanks are 10 kpa, and 20 kpa as shown in Figure below. The friction factor = 0.0216. The pump can operate properly without cavitation. There are several minor losses: an entrance, an exit, two screwed 90 regular elbows, and two fully open screwed globe valves. Density of water = 1000 Kg/m dynamic viscosity of water = 0.1 Pa.s. Derive equation describes the relation between the flow rate Q m/s and the head required by the system (hp).
