Heat Calculations

Heat Dissipation Capacity of Steel Reservoirs

0.001 X Surface Area X Difference between oil and air temperature
If the oil temperature is 140 degrees, and the air temperature is 75 degrees, how much heat will a reservoir with 20 square feet of surface area dissipate?

Surface Area = 20 square feet
Temperature Difference = 140 degrees - 75 degrees = 65 degrees
0.001 X Surface Area X Temperature Difference = 0.001 X 20 X 65 = 1.3 horsepower

Note: 1 HP = 2,544 BTU per Hour

Heating Hydraulic Fluid

1 watt will raise the temperature of 1 gallon by 1 degree F per hour
and
Horsepower X 745.7 = watts
and
Watts / 1000 = kilowatts
