Question

The heat transfer is given by ___________

(a) Q = UA ΔT

(b) U = QA ΔT

(c) U = AQ ΔT

(d) Q = U ΔT

The question was posed to me by my college director while I was bunking the class.

My question is taken from Large Capacity Fermenters in division Fermentation System & Management of Fermentation Technology

Answer 1

The correct option is (a) Q = UA ΔT

Best explanation: The transfer of heat from beer to coolant involves the combination of convection and conduction. It can be given by heat transfer formula: Q = UA ΔT where Q is the rate of heat transfer, U is the overall heat transfer coefficient, A is the area of the jacket, and ΔT is the difference in temperature between two liquids.
