Selection Procedure Step 1 Determine Heat Load. Typical Rule of Thumb, -size cooler for 1/3 of the input horsepower. Heat load may be expressed as either Horsepower or BTU/Hr or KW/°C. HP=BTU/HR ÷ 2545 Metric Version Corrected Heat Rejection Step 4 Select Model From Curves Enter the Performance Curves at the bottom with the GPM oil flow and proceed upward to the adjusted Heat Rejection from Step 3. Any Model or Curve on or above this point will meet these conditions. Step 2 Determine Entering Temperature Difference. Step 5 Calculate Oil Pressure Drop Find the oil pressure drop Entering oil...
