Water is pumped from a lake at ambient pressure and temperatur to an elevaltion of 15 m through a pipe of 2-cm diameter galvanized iron at a flow rate of 0.00366 m^3/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
