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.

How to Calculate Head Loss?

Head Loss calculator uses Head Loss due to Friction = (Friction Factor*Pipe Length*Fluid Average Velocity^2)/(2*Pipe Diameter*[g]) to calculate the Head Loss due to Friction, The Head Loss formula is defined as a measure of the reduction in the total head (sum of elevation head, velocity head, and pressure head) of the fluid as it moves through a fluid system. Head Loss due to Friction is denoted by H_f symbol.
