Two tanks are connected by a network as shown below. The length of the piping segments A through F are 5,1,2,1.8,4 and 3m. The difference in height between the water level and the pipe outlet is 7m(H); the valve is a fully open gate valve, and there are three elbows, two 45 and one 90. The pipe diameter is 0.50m with roughness 0.01m, and a fluid is flowing through at 12.5m/s with density 800kg/m3 and viscosity 1Pas. The pump is operating on 98105W of power at 29% efficiency. Determine the pressure head, in metres, at the outlet of the pipe to 1 decimal place
