1.	Heat transfer co-efficient, hԍ(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 hԍ = 0.0176G^0.8. But when the flow of air perpendicular to the surface is encountered, this equation changes to
A.	hԍ = 1.004G^0.37
B.	1.004G^0.8
C.	hԍ = 0.0176G^0.37
D.	0.0176G^1.37
Answer» B. 1.004G^0.8
