For the system shown in Figure 7, water flows through the pump at a rate of 50 Liter/s. The allowable Net Positive Suction Head (NPSH) provided by the manufacturer at this flow rate is 3.2 m. Determine the maximum height 'H' above the water surface at which the pump can be located to operate without cavitating. Data: Pipe diameter, D= 10 cm; Pipe roughness, e = 0.00002; Patm = 101 kPa; Vapor pressure of water, P, (at 20 °C) = 2340 Pa; Density of water (p) = 998 kg/m³; Viscosity of water (4) = 1.002 × 10³ Pa.s. 4 m Reentrant Entrance (K=0.8) H Water at 20 °C 7 m Elbows (K=0.19) Figure 7 Pump
