(γ is the specific weight: and hf is the loss of head due to friction)
  • a)
    γQ(H - hf)
  • b)
    γQH
  • c)
    γQ(H + hf)

The power transmitted through a pipe is maximum when the loss of head due to friction is given by (H = head supplied),
hf = H/3
Power transmission through pipes: 
  • Power is transmitted through pipes by flowing water or other liquids through them. 
  • Power transmitted through pipes will be dependent over the following factors as mentioned here. 
  1. Rate of flow through the pipe.
  2. Total head available at the end of the pipe
Now we will consider a tank with which a pipe AB is connected. Let us consider the following terms from figure

L = Length of the pipe, D = Diameter of the pipe, H = Total head available at the inlet of the pipe, V= Velocity of flow in the pipe, hf = Loss of head due to friction, f = Co-efficient of friction 
Power transmitted at the outlet of the pipe can be determined by:
P = γQHnet
P = ρQgHnet

The power available at the outlet of the pipe can be calculated using the formula:

Power = (Q * H * 9.81)/1000

where Q is the flow rate of water in cubic meters per second, H is the head of water in meters, and 9.81 is the acceleration due to gravity in meters per second squared.

The division by 1000 is to convert the power from watts to kilowatts.
