Question

Write the equation to estimate heat flow q due to convection.

Answer 1

q= h ΔT

Step-by-step explanation:

Heat flow due to convection given as follows

Q= h A ΔT

Heat flux per unit area given as

q= h ΔT

Where h is the heat transfer coefficient,A is the surface area and ΔT is the temperature difference.

Lets take one plate having temperature
`T_1` and air is flowing on the plate with temperature
`T_2` and air having heat transfer coefficient h.Dimensions of plate is l x b.

Area of plate

`A=lbm^2`

So heat transfer

`Q=h* l* b(T_1-T_2)`
