Pipe Diameter Formula

Diameter of Pipe = (Friction Factor*Length*(Average Velocity^2))/(2*Head Loss Due to Friction*Earth’s Geocentric Gravitational Constant)
D = (f*L*(V_avg^2))/(2*H_f*GM)

Why is it called head loss?

The pressure head is due to the static pressure, the internal molecular motion of a fluid that exerts a force on its container. Resistance head (or friction head or Head Loss) is due to the frictional forces acting against a fluid's motion by the container.
