About the Piping & Structural Calculators
Piping and structural calculators assist HVAC engineers with the mechanical and physical aspects of system installation. This section includes tools for totaling hydronic piping pressure drop and finding the curb height difference needed to level rooftop equipment on pitched surfaces. The pressure drop tool adds friction over the run and its fittings, at a friction rate you enter, to the static lift of any vertical rise. Use them during design when checking pump head or detailing roof curbs for a given pitch, and in the field to verify that installed piping and curbs will perform as designed.
