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 0.0176G1.37 1.004G0.8 HG = 1.004G0.37 HG = 0.0176G0.37 0.0176G1.37 1.004G0.8 HG = 1.004G0.37 HG = 0.0176G0.37 ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design Tube wall thickness depends on the cor-rosiveness of the fluids and their operating pressure & temperature and is specified by Birmingham wire gauge (B.W.G)-a number which varies from 8 to 18 with the numbers 14 and 16 being more commonly used. Outside diameter of tubes varies from about 15 to 50 mm; however a tube of less than __________ mm outside diameter is generally not recommended for fouling fluids. 28 19 38 16 28 19 38 16 ANSWER DOWNLOAD EXAMIANS APP
