Free hydraulic calculator for fire sprinkler hydraulic calculations
Hcalc is a simple hydraulic calculator which we originally developed for use with our FHC training courses to help teach some of the fundamental hydraulic principles which are so important in fire sprinkler design. We believe that all fire protection engineers should have a good understanding of the principles of hydraulic calculations to enable them to optimise designs and to 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 principals of hydraulics in fire protection engineering, checking calculations or for solving simple hydraulic calculations for fire sprinkler, hydrant, hose reel and other types of water based fire protection systems.

Fire protection engineers and consulting engineers from around the world have installed Hcalc to help them with calculations and the verification.
Pipe pressure loss calculations
With Hcalc you can calculate the friction loss in a circular pipe using the Hayes and Williams pressure loss formula which is specified in NFPA 13 and EN 12845. You can specify the pipe size, flow rate and the pipes C factor and will calculate the pressure loss per metre, for the total pipe length and the water velocity. You can select the type of pipe material from the drop-down list or enter your own pipe C factor.
Whenever you need to carry out pressure loss calculation or to verify the simple calculator is ready to help.
Flow from a sprinkler head
With Hcalc Spk 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 of remembering the formula.
The K factor formula is one of the basic building blocks of fire sprinkler design and fire protection hydraulic calculations and most of us will have committed it to memory. But now you can have this simple tool sitting on your desktop so you no longer need to find your calculator or pen and paper.
Hcalc Is compatible with the following Microsoft operating systems
Windows 10 (32 and 64-bit editions), Windows 8 & 8.1 and Windows 7
Hydraulics for engineers
If you have an interest in hydraulic calculations and the formulas associated with then then we have an excellent series of articles which will enhance your skills as a fire protection engineer.
Hcalc is easy to use but will have still provided an on-line manual and a short tutorial video to help get you started.
You will also find all the formulas which have been used clearly set out and with additional information.
