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.	G = 1.004G0.37
B.	.004G0.8
C.	G = 0.0176G0.37
D.	.0176G1.37
