Elkhart Hard Facts Calculator
This puts everything needed for accurate flow testing at your fingertips with all the necessary calculators in just one easy to use application.
Calculators are included for the following:
• Smooth Bore Discharges & Flow/Pressure
• Nozzle Reaction for Smooth Bore Nozzles
• Nozzle Reaction for Fog Nozzles
• Pump Discharge Pressure for standard layouts, with ability to input hose coefficient depending on make and inside diameter
• Pump Discharge Pressure with elevation changes and appliances
• Pump Discharge Pressure for High-Rise layouts
• Fire Flow Formula Calculators for both the NFA and Iowa Formulas
Also included are direct links to several Brass Tacks & Hard Facts videos such as how-to setup and calibrate a flowmeter to measuring nozzle pressure. View the entire library at BrassTacksHardFacts.com.

Calculated pressure is barely readable because it's cut off. 5 stars if that gets fixed.

The "Engine Pressure" line in the calculator is half cut-off. If that's fixed I'd give it 5 stars.

Need to fix the answer line and it would be perfect!!!!
The calculated GPM or PSI is cut off at the bottom of the application. It's barely readable. This has been mention over a year ago in the reviews here. Is anything ever going to be done to fix it?
