Example For the parallel Multiple pipe loop system. of Fig. P6.116, all pipes are 8-cm-diameter asphalted cast iron. If the total pressure drop pi- P2 = 750 kPa, find the resulting flow rate Q m'/h for water at 20°C. Neglect minor losses. the friction factor from the Moody-chart fully rough regime fouch = 0.022 . For water at 20°C, take p = 998 kg/m and u = 0.001 kg/m-s. For asphalted cast iron, e= 0.12 mm, hence add = 0.12/80 = 0.0015 for all three pipes. The head loss is the same through AC and BC.

02 h, are 12m. The pump efficiency is 79%, and the pump is driven by an electric motor. A pump moves water @10°C from a lake into a large, pressurized holding tank as shown. The flow rate, Q. is 375 L/min, and the piping system losses, 1) Sketch the setup (simple schematic is good), 2) label the z datum, and 3) identify and label the boundary conditions (P, V, and z) at 1 and 2 for use in a) the General Energy Equation (GEE). Provide values and units for the boundary conditions. Hint: For identifying good locations for boundary conditions, where are the velocities approximately zero? b) Calculate the head added to the fluid, h,, by the pump. Give your answer in units of m. Hint: Be careful with signs in manipulating the GEE. Show as many steps as you need to get your h, equation correct. Calculate the power added to the fluid by the pump in units of kW.
