Two water reservoirs A and B are connected to each other through a 35m-long, 2-cm-diameter cast iron pipe with a sharp-edged

Two water reservoirs A and B are connected to each other through a 35m-long, 2-cm-diameter cast iron pipe with a sharp-edged entrance. The pipe also involves a swing check valve and a fully open gate valve. The water level in both reservoirs is the same, but reservoir A is pressurized by compressed air while reservoir B is open to the atmosphere at 94 kPa. If the initial flow rate through the pipe is 1.2 L/s, determine the air pressure (gage) in kPa on top of reservoir A. Take p=999.7 kg/m3,J=1.307x10-3 Pas and e=0.260mm Air co 2 cm Element K Sharp inlet 0.5 Well-rounded inlet 0.25 Globe valve 1.5 Swing check-valve 2 Gate valve (open) 0.2 Gate valve (50%) 0.5 Exit

    Water (density 998 kg/mº, dynamic viscosity 0.001 Pa s) is pumped between two reservoirs at a volumetric flow rate of 0.006 m/s through a 120-m long pipe of 5 cm diameter. The roughness ratio of the pipe is a/d = 0.001. There are some fittings and valves in the pipe system, as shown in Figure Q1. The loss coefficients of the valves and fittings can be found in Table Q1. The Darcy friction factor can be found in the Moody...
