Definition of Head and its Units | Kinetic Head | Potential Head | Pressure Head | Total head

Head : (H)

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

Units:

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
