Schedule 40 steel pipe, 50.8 mm diameter is used to construct a piping system. The length of piping is 100 m and there are 4 standard elbows, 2 tees one Gate and Globe Valve. If the flow is 25Litres/Sec, what is the friction head of the system?
Useful data from tables: Equivalent resistance (length of pipe of same diameter) for Sch. 40 Pipe and fittings:
Friction loss at 25 L/Sec Flow = 36.5 (m water/25 m of pipe)
Elbows = 1.68; Tees = 3.35; Globe Valve = 17.4; Gate Valve = 0.37
