Evaporator machine but in the operations manual

[TonyB]

Hello,

Could someone please give me an explanation using the following equation?

I work this evaporator machine but in the operations manual there is this equation below.I would like to further my knowledge.

Equation for Evaporation
Q = U x A x DT

Q = Energy Transfer (W)
U = Heat Transfer coefficient (W/m2°K)
A = Heat Transfer area (m2)
DT = Temperature difference (°K)

Please any help appreciated...thank you...Tony

The equation is a relationship between the energy transfer rate (power), the surface area, and the mean temperature gradient at that surface. It more or less is used to define the heat transfer coefficient.

Q = U x A x DT or

U = Q/(A*DT)

U is an empirical correlation or coefficient.
