Calculate Head Loss in a Pipe







Formula

The formula to calculate the Head Loss (HL) is:

\[ HL = \frac{f \cdot L \cdot V^2}{2 \cdot g \cdot D} \]

What is Head Loss?

Head loss is the reduction in the total head (sum of pressure head, velocity head, and elevation head) of the fluid as it moves through a fluid system. This loss is due to the friction between the fluid and the pipe walls, as well as the friction between the fluid particles themselves as they flow. It is an important factor in the design and analysis of fluid systems such as water supply networks, heating systems, and chemical processes.

Example Calculation

Let's assume the following values:

Using the formula to calculate the Head Loss (HL):

\[ HL = \frac{f \cdot L \cdot V^2}{2 \cdot g \cdot D} = \frac{0.02 \cdot 100 \cdot 5^2}{2 \cdot 32.2 \cdot 0.5} ≈ 1.55 \text{ feet} \]

The Head Loss (HL) is approximately 1.55 feet.
