Heat Calculations

Heat Dissipation Capacity of Steel Reservoirs:

0.001 x Surface Area x Difference between oil and air temperature

Example: If the oil temperature is 140 degrees farenheit, and the air temperature is 75 degrees farenheit, how much heat will a reservoir with 20 square feet of surface area dissipate?

Surface Area = 20 square feet
Temperature Difference = 140ºF - 75ºF = 65ºF
0.001 x Surface Area x Temperature Difference = 0.001 x 20 x 65 = 1.3 horsepower

Heating Hydraulic Fluid Notes:

• 1 HP = 2,544 BTU per Hour

• 1 watt will raise the temperature of 1 gallon by 1ºF per hour

• Horsepower x 745.7 = watts

• Watts ÷ 1000 = kilowatts
