Heat Transfer Calculator
Calculate heat transfer using overall heat transfer coefficient.
How to Use This Calculator
1
Enter U
Overall heat transfer coefficient.
2
Enter A
Effective heat transfer area.
3
Enter ΔT
Driving temperature difference.
Formula
q = U × A × ΔT
Example: U=100, A=5, ΔT=20 → q=10,000 W
About Heat Transfer
Overall heat transfer combines conduction, convection, and radiation effects.
Frequently Asked Questions
Is ΔT LMTD?
For exchangers, ΔT is often the log-mean temperature difference.
Difference vs calorimetry?
Calorimetry uses m·c·ΔT; this uses overall U and area.
