3) The system in Figure below consists of 1200 m of 5 cm cast-iron pipe, two 45° and four 90° flanged long-radius elbows, a fully open flanged globe valve, and a sharp exit into a reservoir. If the elevation at point 1 is 400 m, what gage pressure is required at point 1 to deliver 0.005 m3/s of water at 20°C into the reservoir? (For water at 20°C, take p-998 kg/m3 and u-0.001 kg/m-s.

A pump is used to pump water at 60oF from a reservoir whose surface is 4.0 ft above the centerline of the pump inlet. The piping system from the reservoir to the pump consists of 10.5 ft of cast iron pipe with a diameter of 4.0 in and an average roughness (ε) of 0.02 inches. There are several minor losses: a sharp edged inlet (K – 0.5), three flanged smooth 90o regular elbows (K – 0.3 each), and a fully open flanged globe...

The system shown in the diagram consists of 1200m of cast-iron pipe with an internal diameter of 5cm (roughness of 0.00015 ft), two 45o and four 90o long radius elbows, a fully open bevel seat globe valve, and a sharp exit into a reservoir. If the elevation difference between the inlet and level in the reservoir is 10m, what gauge pressure is required at point 1 to deliver 0.005m^3/s of water at 20oC into the reservoir (use density of 998.2...

Water (p=998kg/m^3,
u=0.001Pa*s) flows from reservoir A to reservoir B through the
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
100L/min by reducing the length of the 25mm pipe. What must new
length of the 25mm pipe be?

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)...
