1. 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
(A): are easier to clean.
(B): are less prone to fouling.
(C): can be fitted into a smaller shell diameter hence the cost of the heat exchanger would be less.
(D): none of these.
