PLUMBING FORMULATOR contains over 120 formulas that are useful for plumbers and HVAC installers. The program calculates areas of pipe walls. It calculates the weights of different pipes. PLUMBING FORMULATOR also calculates the final temperature when two bodies of water are mixed. It calculates expansion of pipes, radiant heat and heat loss. The Plumbing Formulator has various formulas to calculate area and volumes of differing shapes. The program also includes dozens of conversions from everything from square feet to square inches to pounds square inches to feet of water.

Every result in PLUMBING FORMULATOR can be Emailed and printed. You can also select from favorites and recent formulas. In the coming months there will be program updates that will include additional formulas.

Ct plumber and pipefitter ,

Awesome start

So many things can be added .. Spoke with them and they said soon they will ....must have app ....

Don't waste your money.

Memorize 1.414 for 45 offsets and get a Frankland book. Totally useless. Who's going to know the ID of 3" copper tubing so the app can figure out the weight per foot? It depends on the tubing type...bottom line why calculate this when this info is readily available. How about instead ask me for tubing size, tubing type (DWV, K, L, M, ACR/MED) and the length to calc weight per ft dry and wet. No...let me get my calipers and measure the ID...stupid.

Not so much

Does not calculate right I entered 20 ft of cast iron 4 in pipe and it told me it weighed two point six pounds
