Greetings all, I am looking to collect a list of everyone's favorite on line calculator they use in their calculation. One of my favorite is the Shipco one for quickly sizing a boiler feed unit.

I am a huge fan of the construction master for dealing with feet, inches and fractions. You do have to pay for the full version. https://www.calculated.com/mobile/prd457/Construction-Master-Pro-App.html

The B&G System sizer app works well for estimating head loss in the field.

I am still looking for an app that I like as well as my Ductalator. I have tried a bunch and haven't found one yet.

For online computer apps, Engineering Toolbox is a nice one for lot's of stuff. I like Flatplate and B&G for heat exchangers.

@RayWohlfarth ask this on the boiler guy facebook page, I bet they will have a lot of recommendations as well. Especially geared towards Commercial / industrial.

More of a graph, handy none the less for seeing velocity at various flow rates.
