Process Equipment and Plant Design Correct use of 'factor of safety' is very important in equipment design. It is defined as the ratio of the Working stress to ultimate stress Ultimate stress to breaking stress None of these Ultimate stress to working stress Working stress to ultimate stress Ultimate stress to breaking stress None of these Ultimate stress to working stress ANSWER DOWNLOAD EXAMIANS APP
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 = 1.004G0.37 1.004G0.8 0.0176G1.37 HG = 0.0176G0.37 HG = 1.004G0.37 1.004G0.8 0.0176G1.37 HG = 0.0176G0.37 ANSWER DOWNLOAD EXAMIANS APP
