Process Equipment and Plant Design In a multipass shell and tube heat exchanger, the baffles on shell side is primarily provided for Reducing scale deposition Fixing the tubes Creating turbulence Increasing pressure drop Reducing scale deposition Fixing the tubes Creating turbulence Increasing pressure drop 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 None of these Are easier to clean Are less prone to fouling Can be fitted into a smaller shell diameter hence the cost of the heat exchanger would be less None of these Are easier to clean Are less prone to fouling Can be fitted into a smaller shell diameter hence the cost of the heat exchanger would be less ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design In a shell and tube heat exchanger, the 'tube pitch' is defined as the None of these O.D. of the tube for square pitch Shortest centre to centre distance between adjacent tubes Shortest distance between two adj acent tube holes None of these O.D. of the tube for square pitch Shortest centre to centre distance between adjacent tubes Shortest distance between two adj acent tube holes ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design Mc Cable Thiele method used for finding theoretical stages in a distillation column assumes that the Sensible heat differences are small, because the temperature changes from tray to tray is small Liquid/vapor loading across the column remains constant All of these Trouton's rule is applicable Sensible heat differences are small, because the temperature changes from tray to tray is small Liquid/vapor loading across the column remains constant All of these Trouton's rule is applicable ANSWER DOWNLOAD EXAMIANS APP
