Heat Dissipation Capacity of Steel Reservoirs
  • Surface Area (sq ft)
  • Temp Diff (°F)

  • Heat Dissipation

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

Formula: 0.001 x Surface Area x Difference between oil and air temperature = horsepower

Heating Hydraulic Fluid Nodes:

  • 1 HP = 2,544 BTU per Hour
  • 1 watt will raise the temperature of 1 gallon by 1°F per hour
  • Horsepower x 745.7 = watts
  • Watts ÷ 1000 = kilowatts
