Process Equipment and Plant Design A perforated plate has holes of diameter dh arranged in a pitch ph. Each hole has a tube of I.D. dt passing through it. The ligament efficiency is given by (ph - dt)/ph (ph - dh)/dh (ph - dh . dt/2)/ph (ph - dh)/ph (ph - dt)/ph (ph - dh)/dh (ph - dh . dt/2)/ph (ph - dh)/ph 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 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 Can be fitted into a smaller shell diameter hence the cost of the heat exchanger would be less ANSWER DOWNLOAD EXAMIANS APP
