Process Equipment and Plant Design The maximum liquid gradient over a tray must not exceed 5" 2"-3.5" 0.5" -1.25" Half the tray spacing 5" 2"-3.5" 0.5" -1.25" Half the tray spacing 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 None of these Are easier to clean Can be fitted into a smaller shell diameter hence the cost of the heat exchanger would be less Are less prone to fouling None of these Are easier to clean ANSWER DOWNLOAD EXAMIANS APP
