Process Equipment and Plant Design In the design of a shell and tube heat exchanger, the corrosion allowance For internal cover and tube sheet is provided on both the sides For carbon steel and cast iron pressure parts is 1.5 mm (except for tubes) and for severe conditions it is 3 mm All of these Need not be provided for non-pressure parts like tie rods, spacers, baffles, supports etc For internal cover and tube sheet is provided on both the sides For carbon steel and cast iron pressure parts is 1.5 mm (except for tubes) and for severe conditions it is 3 mm All of these Need not be provided for non-pressure parts like tie rods, spacers, baffles, supports etc 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 0.0176G1.37 HG = 1.004G0.37 HG = 0.0176G0.37 1.004G0.8 0.0176G1.37 HG = 1.004G0.37 HG = 0.0176G0.37 1.004G0.8 ANSWER DOWNLOAD EXAMIANS APP
