Question

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: (a).hԍ = 1.004G^0.37
