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.

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.
