Answer to Question #336418 in Civil and Environmental Engineering for Aryan

Question

A tank is situated at top of a house. RL of ground was kept as 200 m while the RL of the

terrace was measured to be 206.5 m. The RL of top of tank was found to be 208 m. An orifice

is placed at the bottom of the tank (Cd = 0.65) having diameter of 40 mm. A pipe was fit to

the orifice having diameter of 40 mm and diameter of the pipe was suddenly increased to 100

mm. Bend of 90o was provided and a gate valve is provided to control the flow. Just before

the tap a bend of 90o was again provided and a sudden contraction was provided and pipe

diameter was reduced to 20 mm. Calculate the discharge coming out from the tap if the total

length of pipe is 120 m (10 m 40 mm pipe, 90 m 100 mm pipe and 20 m 20 mm pipe) and

pipe is made up of steel with f = 0.015 if
