To calculate the Head Loss due to friction:
\[ h_f = f \left(\frac{L}{D}\right) \left(\frac{v^2}{2g}\right) \]
Where:
Pipe friction loss refers to the pressure drop that occurs as a fluid flows through a pipe due to the friction between the fluid and the walls of the pipe. When fluid flows through a pipe, it experiences resistance from the pipe’s inner surface, which results in a loss of pressure along the length of the pipe.
This phenomenon is important for engineers and designers involved in fluid flow systems as it directly impacts the efficiency and effectiveness of the system. By understanding pipe friction loss, engineers can accurately calculate the pressure drop and select appropriate pipe sizes, pumps, and other equipment required to maintain the desired flow rate.
As fluid flows through a pipe, it loses energy in the form of pressure due to frictional resistance. This pressure loss can lead to a decrease in flow rate and may require additional energy, such as increased pump power, to maintain the desired flow.
Let's assume the following values:
Using the formula:
\[ h_f = 0.02 \left(\frac{100}{0.5}\right) \left(\frac{2^2}{2 \times 9.81}\right) = 0.82 \text{ meters} \]
The head loss is 0.81 meters.
Let's assume the following values:
Using the formula:
\[ h_f = 0.03 \left(\frac{200}{0.3}\right) \left(\frac{3^2}{2 \times 9.81}\right) = 9.17 \text{ meters} \]
The head loss is 9.17 meters.
