Points) Water at 15°C is to be discharged from a reservior at a rate of 18 L/s using two horizontal cast iron pipes (= 0.00026 m) connected in series and a pump between them. The first pipe is 25 m long and has a 8-cm diameter, while the second pipe is 35 m long and has a 4-cm diameter. The water level in the reservoir is 28 m above the centerline of the pipes. The pipe entrance is sharp edged (K₁ = 0.5), and losses associated with the connection of the pump are negligible. Determine (a) the required pumping head and (b) the minumum pumping power to maintain the indicated flow rate. (c) If the pump is 80 percent efficient, what horsepower pump is needed?
