Question
What is the cause of convection heat transfer in
evaporators? A. Convection is heat transfer by neutrons B. Convection is heat transfer by mass motion of a heat source C. Convection is mass transfer by mass motion of a fluid D. Convection is heat transfer by mass motion of a fluidSolution
Explanation: Convection is heat transfer by mass motion of a fluid like water, air. Due to this movement the heated fluid moves away from the source of heat and thus carrying energy with it.
