Hcalc is a simple hydraulic calculator we originally developed for use with our FHC training courses to help teach some of the fundamental hydraulic calculations & principles which are so crucial 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 optimize designs and to ensure that all calculations can be properly checked and verified.

A two-page A4 reference covering the fundamental equations used in fire sprinkler and water mist hydraulic calculations, with worked examples throughout. Page one covers the K-factor equation, design density, velocity in a pipe, static head pressure, and the full form of the Hazen-Williams equation with a C-factor table for common pipe materials. Page two covers the Hazen-Williams short-form equation with Kp values for steel and CPVC pipes, a symbols and units reference, and links to the free online hydraulic calculators at canutesoft.com. Suitable for engineers who need a quick reference during hand calculations or when checking FHC results.
