Head : (H)

The total energy of the fluid particles per unit weight is known as head.


The unit of head is meter.

Following are different types of head.

  • Kinetic Head :

Kinetic energy per unit weight of the fluid is known as kinetic head.

K.H= v2/2g

  • Potential Head :

Potential head is the potential energy per unit weight.

Potential head = z

  • Pressure Head :

It is the pressure energy per unit weight.

Pressure head=p/γ

  • Total Head :

The sum of all heads will be the total head.

T.H=v2/2g+ z + p/γ
