Process Equipment and Plant Design For a cylinderical vessel of moderate height, the weld joint efficiency for joints parallel to the cylinderical axis is given as 1.0, while for joints along the girth (circumference) it is given as 0.8. In calculating the shell wall thickness using code formula for an internally pressurised cylinderical vessel, what value of weld joint efficiency should be used? (0.8)0.5 0.9 1 0.8 (0.8)0.5 0.9 1 0.8 ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design In a shell and tube heat exchanger for a given heat transfer surface area, smaller diameter tubes are favoured as compared to larger diameter ones ; because the smaller diameter tubes Can be fitted into a smaller shell diameter hence the cost of the heat exchanger would be less Are less prone to fouling Are easier to clean None of these Can be fitted into a smaller shell diameter hence the cost of the heat exchanger would be less Are less prone to fouling Are easier to clean None of these ANSWER DOWNLOAD EXAMIANS APP
