State Newton’s Law Of Convection?

Answer :

Heat transfer from the shifting fluid to solid surface is given through the equation.

Q = h A = [Tw – T∞]

This equation is called Newton’s regulation of cooling.
Where h = Local warmth switch coefficient in W/m2K.
A = Surface vicinity in m2
Tw = Surface [or] Wall temperature in K.
T∞ = Temperature of fluid in K.
