Heat Transfer Coefficient Calculator

Find the convective heat transfer coefficient.

Heat transfer rate (W)

Area

Temperature difference (K)

Heat transfer coefficient (W/(m²·K)) 10

Formula: h = Q ÷ (A·ΔT)

Step-by-step with your numbers:

1. Values used:

2. Heat transfer rate = 500 W

3. Area = 2

4. Temperature difference = 25 K

6. Heat transfer coefficient = (500 / 100) x 2 = 5 x 2 = 10W/(m²·K)

Did we solve your problem today?

The convective heat transfer coefficient measures how readily heat moves between a surface and a fluid.

The math behind it

From Q = h·A·ΔT, solve h = Q ÷ (A·ΔT).

500 W over 2 m² with ΔT 25 K → h = 10 W/(m²·K).

What raises h?

Faster fluid flow and turbulence greatly increase convective transfer.
