Hcalc - Hydraulic calculator

Hcalc is a simple hydraulic calculator, initially developed for use with our FHC training courses to help teach some of the fundamental hydraulic calculations & principles that are so important in fire sprinkler design. All fire protection engineers should understand the principles of hydraulic calculations to optimize designs and ensure that calculations can be properly checked and verified.

Fire sprinkler engineers, inspectors, and insurance companies will find a use for our free Hcalc - Hydraulic Calculator. It can be used for teaching the principles of hydraulics in fire protection engineering, checking calculations or solving simple hydraulic calculations for fire sprinklers, hydrants, hose reels and other types of water-based fire protection systems.

Hazen Williams pressure loss formula

With Hcalc, you can calculate the friction loss in a circular pipe using the Hayes and Williams pressure loss formula specified in NFPA 13 and EN 12845 and in many other international design standards.

 

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.

Sprinkler head - K-factor calculation

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.
