Hcalc
Hydraulic Calculator

You can specify the pipe size, flow rate, and the pipe C-factor, and then Hcalc will calculate the pressure loss per meter and for the total pipe length together with velocity. You can select the type of pipe material from the drop-down list or enter your pipe C-factor.

Whenever you need to carry out or verify pressure loss calculations, the simple calculator is ready to help. 

With Hcalc - Sprinkler Flow, you can solve any of the three variables in the K-Factor formula, the flow from the sprinkler, the pressure required at a sprinkler and the K-Factor without the need to remember the formula.

The K-factor formula is one of the basic building blocks of fire sprinkler design and fire protection hydraulic calculations, most of us will have committed it to memory, but now with Hcalc, you no longer need to. In addition, this simple tool can be on your desktop, so you no longer need to find your calculator or pen and paper. 

You can use Hcalc for any fire sprinkler, water mist nozzle, or any other nozzle or head for which you have a K-Factor, this could be a hose reel nozzle, a foam monitor or a fire hydrant.
