**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= v^{2}/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=v^{2}/2g+ z + p/γ
