How the calculation works
A = Q ÷ (U × F × LMTD), then the selected fouling/design margin is added.
What to verify
Thermal design also requires pressure drop, phase change, fouling resistance and mechanical-code checks.
How accurate is this calculator?
It is a transparent planning calculation based on the entered values and stated assumptions. Verify inputs and obtain professional or supplier confirmation where the decision is consequential.
Does it use U.S. defaults?
Yes. U.S. units, terminology, pricing conventions and rules are the primary defaults where location matters.
Is data sent to a server?
No. The calculation runs locally in the browser and does not send entered values to a remote calculation service.
