Process Equipment and Plant Design Number of evaporators which can be used in service in a multiple effect evaporation system is limited by the Both A & B Neither A nor B Economic limit reached, when the plant cost exceeds the saving of steam Practical limit reached, due to low heat transfer rate because of inadequate temperature difference Both A & B Neither A nor B Economic limit reached, when the plant cost exceeds the saving of steam Practical limit reached, due to low heat transfer rate because of inadequate temperature difference 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
Process Equipment and Plant Design In case of a shell and tube heat exchanger, the minimum shell thickness for carbon steel (inclusive of corrosion allowance) depends on shell diameter and is in the range of __________ mm. 44058 43962 44183 43895 44058 43962 44183 43895 ANSWER DOWNLOAD EXAMIANS APP
