Result Interpretation

NFPA 15 & API RP 2001 Fire Water Demand Calculator computes Fire water flow rate in L/min using the defined engineering formula and the input values provided. Fire water flow rate is expressed in L/min. No universal acceptance threshold is defined by this calculator.

Worked Example

Verified calculation

Given:

  • Exposed surface area = 50
  • Application density = 10.2
  • System correction factor = 1

Expected Result:

  • Fire water flow rate = 510

Engineering Interpretation:

Under the given input conditions, the calculated result is: Fire water flow rate = 510 L/min.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from automatically validated test cases.
