| Formula For: | Word Formula | Letter Formula |
| Reservoir Cooling Capacity Based on Adequate Air Circulation |
Heat (BTU/HR) = 2 x Temperature Difference Between Reservoir Walls And Air (ºF) x Area of Reservoir (Sq.Ft.) |
BTU/Hr = 2.0 x T x A |
| Heat in Hydraulic Oil (approx.) Due to System Inefficiency(SG=.89-.92) |
Heat (BTU/HR) = Flow Rate (GPM) x 210 x Temperature Difference (ºF) |
BTU/HR = Q x 210 x T |
| Heat in Fresh Water (approx.) | Heat(BTU/HR) = Flow Rate (GPM) x 500 x Temperature Difference (ºF) |
BTU/HR = Q x 500 x T |
| Note: One British Thermal Unit (BTU) is the amount of heat required to raise the temperature of one pound of water one degree. Once Horsepower = 2545 BTU/HR. | ||
