8 Services from plumbing-calc.x402tookit.com

Calculates how much a pipe run lengthens or shortens due to a temperature change for copper, steel, PVC, CPVC, PEX, or ABS materials, returning results in both inches and millimeters.

Returns the smallest standard copper Type L or PVC Schedule 40 pipe nominal size that keeps water velocity under a specified maximum for a given flow rate.

Calculates water velocity in feet per second from flow rate and pipe size, or calculates the flow a pipe carries at a given velocity, for copper Type L or PVC Schedule 40 pipe.

Calculates the volume of water held in a pipe run in gallons and litres (per foot and total), given nominal pipe size or inside diameter and pipe length.

Calculates the fall needed for a drain run at a given slope in inches per foot, or derives the slope from a measured fall, and compares against typical plumbing code minimums.

Calculates friction pressure loss in PSI (and feet of head) over a pipe run using the Hazen-Williams formula, given flow rate, pipe size, length, and C factor.

Calculates the time in hours and minutes to fill or drain a tank given inflow rate in GPM, tank volume or round tank dimensions, and an optional simultaneous outflow rate.

Calculates water flow rate in GPM and litres per minute from a simple bucket test (volume and fill time), plus hourly and daily usage estimates.
