The Hydraulic Heat Calculator is a valuable tool that can help in designing, troubleshooting and correcting heat issues within a system. There are many calculation screens that can be used to determine heat generation from pumps/motors, Tank heat dissipation, Radiator sizing /performance, and others.  

Specific Calculations include:
Enter Oil Volume and Power input to determine rate of temperature change
Enter system flow, inlet and outlet radiator temperatures to determine radiator performance
Enter pressure and oil flow to determine temperature increase and heat generated
Enter motor/pump specs to determine temperature increase and heat generated
Estimate power required to heat oil tanks in cold environments
Estimate tank heat dissipation
Empirical cooling calculation to determine radiator size requirement

All calculations can be done in metric or imperial units.
