Transcribed Image Text:

A steel pipe of 0.075 m inside diameter and length 120 m is connected to a large reservoir. Water is discharged to atmosphere through a gate valve at the free end, which is 6 m below the surface level in the reservoir. There are four right angle bends in the pipe line. Find the rate of discharge when the valve is fully open. (ans. 8.3 dm3/s). The kinematic viscosity of the water may be taken to be 1.14 x 10-6 m²/s. Use a value of the friction factor Cf taken from table 2 which gives Cf as a function of the Reynolds number Re and allow for other losses as follows. at entry to the pipe 0.5 velocity heads. at each right angle bend 0.9 velocity heads. for a fully open gate valve 0.2 velocity heads.
