Pipe Friction Loss Calculation

Friction losses of various pipes are calculated by taking into account the fluid temperature. For now, only water is calculated as fluid.

Explanation : The formula used is the Colebrook – White equation for turbulent current (Re> 4000).
$\frac{1}{\sqrt{f }}=-2\log \left ( \frac{2.51}{Re\sqrt{f}}+\frac{\varepsilon /D}{3.71} \right )$
The friction loss occurring along the pipe is found from the Darcy-Weisbach equation.$\small{h_{f}=f\displaystyle\frac{L}{D}\displaystyle\frac{v^{2}}{2g}} $ mSS or $\small{\Delta P=f\displaystyle\frac{L}{D}\displaystyle\frac{\rho v^{2}}{2} }$ Pa.
Here, $\small f$ is the dimensionless unit friction coefficient, $\small D$ is the inner diameter in meters, $\small Re$ is the dimensionless reynolt number, $\small \varepsilon$ meters. Roughness is the specific mass of water as $\small L$ pipe length, velocity as $v$ m/s, $\rho$ kg/m³.
