Friction Loss / Smooth Nozzle

Can't exit the app with back button. Also, it'd be nice if it would default to standard nozzle pressures when selecting fog/sb.

Needs elevation option and instead of "per 100ft", need a dial to change length. Supposed to remove my need to do math. If I'm still doing math this isn't useful.

needs to be able to change coefficients for various brands of hose. the current settings are far too conservative for today's modern low friction fire hose.

very useful app. would like to see the ability to do hydrant flow test calculations in the future.

Very powerful, informative and handy. Great App

Useless. Hang your phone. Just install it and quickly uninstall it.

If we still have to do math to find the answer what's the point of the calculator.

Love it

A very nice tool for pump operations.

Great APP. Will change to 5 stars when you add 2" hose w/ 1 1/2" couplings to the friction loss chart. 10/4/17 Thank You.....2" added

Hard to use if you have soft buttons, have to rotate it to exit. Fog nozzle would be nice too.

Need to add 2" and 1" diameter hose

Limited size of hose.... unit is not SI

What about wildland fire?

Quick what if calculator

Only way to exit the app is a force close.

15/16 is common and hopefully 113/16 will be soon. If you are willing to convert psi to bar, convert the others too.

Cool app .. Versatile .. Can work things based on GPM or pressure or tip size. Good tool for pump testing BUT .... where the 15/16" and 1 1/8" tip ???

Please add inch and 1/8th very common

The app is missing 15/16th and 1 1/8. Those are most popular.
