Water at a flow rate of 0.012 m3/s travels from the lower reservoir to the upper reservoir. The piping system consists of 220 m cast iron pipe with an inner diameter of 7 cm. The system contains a sharp inlet, two standard 90° elbows, an open gate valve, and sharp submerged exit into the upper reservoir. Use the density of water as 998 kg/m3 and the viscosity as 1.0×10-3 kg/(m*s). The Moody diagram is shown below and on the second page of the equation sheet. Determine the frictional head loss due to the total pipe length. You can use the Moody diagram below or an equation to find the Darcy friction factor. Determine the minor head loses in this system. Determine the power required to operate the pump if it is 85% efficient. Enter only the number, not units in the blank below. Include three digits in your answer and give the numerical answer in kW.
