Prоblem 3 (35 Pоints – Pumping pоwer cаlculаtion in piping systems). A pump delivers kerosene to аn elevated reservoir 8 m higher than the storage tank at ground level, as shown in Figure P.3. The tubing system connected to the pump is 20 m in length and 8 cm in diameter. As depicted in Figure P.3, the tubing system has one reentrant entrance (KL = 1.05), two 90° smooth flanged bends (KL = 0.3 each), a 1/4th closed gate valve (KL = 0.3), and a sharp exit (KL = 1.05). The volumetric flow rate is 0.03 m3/s. Consider a pump efficiency of 70% and that the kerosene properties are: ρ = 804 kg/m3, and
