MCQOPTIONS

1.	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 ____________________?
A.	hG = 1.004G0.37
B.	1.004G0.8
C.	hG = 0.0176G0.37
