Heat transfer co-efficient, hG(Kcal/hr.m2.°C) and mass velocity of air, G (kg/hr.m2 ) for air flow parallel to the surface in case of constant drying rate in batch drying is related as hG = 0.0176G0.8. But when the flow of air perpendicular to the surface is encountered, this equation changes to ________?
AhG = 0.0176G0.37
BhG = 1.004G0.37
C1.004G0.8
D0.0176G1.37
Correct answer
B. hG = 1.004G0.37
Explanation
The correct answer is hG = 1.004G0.37.
