a) W K/m2
b) Wm2K
c) (m2K)/W
d) W/ (m2K)
Answer: a
Explanation: The SI unit of film heat transfer coefficient isW K/m2. The heat transfer through convection between a solid and a fluid is measured using heat transfer coefficient. It depends on 1) Hydrodynamic characteristics of its flow, 2)Hydrodynamic characteristics of its flow and 3) Hydrodynamic and thermal boundary conditions.
