Water is pumped from a lake at ambient pressure and temperature to an elevation of 15 m through a pipe of 2-cm diameter galvanized iron at a flow rate of 0.00366 m3 /s. Assume the discharge is to open atmosphere. The pipe is 70 m long and has 2- 90o threaded bend and one 45o regular elbow, and a gate valve that is half closed.
a. Draw the piping system
b. Find the total friction losses
c. Find the total minor losses
d. Can the minor losses be neglected?
e. Calculate the pump power
