Water is to be withdrawn from a 3-m-high water reservoir by drilling a 1.5-cm- diameter hole in the center of the bottom surface. Disregarding the effect of the kinetic energy correction factor, determine the flow rate of water through the hole for
a) a sharp edged entrance followed by threaded 90° bend and then a 3.5m length of wrought iron pipe and finally a fully open Globe Valve
b) redo a) for the ideal case with no viscous losses

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)...

piping system shown. Each elbow has a minor loss coefficient of
1.2. Each valve has a minor loss coefficient of 3.2. The entrance
and exit are both sharp edged. Determine the flow rate L/min. You
now need to modify the piping system to increase the flow rate to
