Example 3.7: A commercial steel piping system is delivering water at 30°C from pressurized tank A to pressurised tank B as shown in figure below. The internal diameter of the pipe is 2.25 cm. The piping system has a well rounded inlet, 1/4 open gate valve, four 90° flanged bend, two 90° miter bend (with vane) and a sharp exit. The total pipe length is 300 m. Gauge pressure at tank A is 500 bar. If the elevation difference, h is 100 m and water is delivered at 250litre/min. Determined minor losses and gauge pressure at tank B
