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 Can be fitted into a smaller shell diameter hence the cost of the heat exchanger would be less Are easier to clean None of these Are less prone to fouling Can be fitted into a smaller shell diameter hence the cost of the heat exchanger would be less Are easier to clean None of these ANSWER DOWNLOAD EXAMIANS APP
