For the system shown, the fluid reservoir is vented to the atmosphere. The atmospheric pressure is 1x105 N/m, the vapor pressure head is 0.4 m, and the water kinematic viscosity is 106 m/s. The pipe diameter is 30 mm with a total length of 10 m and roughness of 0.06 mm. The flow rate is 0.001 m/s. The two elbows are identical Standard Elbows and the valve is Globe Valve Wide Open. The required NPSH for the pump is 9 m. (a) Determine the total head losses. (b) Determine the available NPSH. (c) Will the cavitation occur? Pump Elbow 2 Elbowl 3 m I Valve
