How to calculate the Power Transmitted through the Pipe. How the power through pipe depends on head loss and what is maximum efficiency of transmission through a pipe?

The power transmitted (in watts) through the pipe

= Weight of water flowing in N/s x Head of water in m

The power transmitted will be maximum when the head lost in friction is equal to one-third of the total supply head.

The maximum efficiency of transmission through a pipe is 66.67 percent.
