Input Parameters

Imperial (°F, BTU, ft)SI (°C, kW, m)

Cooling Load (BTU/hr)

Supply Temperature (°F)

Return Temperature (°F)

Flow Rate GPM

Cooling Load50,000 BTU/hr

Supply Temp44 °F

Return Temp54 °F

ΔT10 °F

Formula:

GPM = \frac{Q}{500 \times \Delta T_{°F}}

Calculation:

GPM = \frac{50000.00}{500 \times 10.00}

Result:

10.00 \text{ GPM}
