Piping Fitting and Valve Losses

Toggle
  1. This calculator can be used to determine the head losses expected for pipe fittings and valves based on the equation: Head Loss=K*V^2/2g.
  2. The calculator automatically determines the velocity based on the inputted flow and nominal piping diameter to arrive at the expected head loss for the fitting or valve.
