Process Equipment and Plant Design 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 HG = 0.0176G0.37 1.004G0.8 0.0176G1.37 HG = 1.004G0.37 HG = 0.0176G0.37 1.004G0.8 0.0176G1.37 HG = 1.004G0.37 ANSWER DOWNLOAD EXAMIANS APP

Process Equipment and Plant Design Practical dividing line between a ductile and brittle materials is suggested, when the ultimate elongation is about 5%. Generally, larger the knuckle radius, stronger is the corner torus section of a head. The knuckle radius provided should be less than __________ of the head. 6% of I.D. 3 times the thickness Either A or B, whichever is smaller Either A or B, whichever is larger 6% of I.D. 3 times the thickness Either A or B, whichever is smaller Either A or B, whichever is larger ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design Smaller sized packings are generally dumped to the packed columns, and the large ones of size greater than __________ mm are stacked individually, which provides better control over bed porosity and offers lower gas pressure drop. 25 150 50 75 25 150 50 75 ANSWER DOWNLOAD EXAMIANS APP
