Head Loss

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

There are a number of factors that affect head loss such as:

  • flow rate
  • corrosion and scale deposits
  • fittings
  • inside diameter of the pipe
  • roughness of the pipe wall
  • viscosity of the liquid
  • length of the pipe
  • straightness of the pipe

Head Loss from Loss Coefficient Formula

\(\large{ h_l = K  \frac { v^2  } { 2g }  }\)

Where:

\(\large{ h_l }\) = head loss

ber of factors\(\large{ v }\) = flow velocity

\(\large{ g }\) = gravitational acceleration

\(\large{ K }\) = loss coefficient

Solve for:

\(\large{ v =  \sqrt{   \frac { 2g h_l  } { K }     }     }\)
