Process Equipment and Plant Design Pick out the wrong statement pertaining to a shell and tube heat exchanger. Disk and doughnut baffle is the most commonly used baffle The maximum value of baffle spacing is equal to the I.D. of the shell The maximum unsupported tube span is generally about 75 times tube diameter, but is reduced to about 60 times for aluminium, copper & alloys of these The minimum value of baffle spacing is 50 mm Disk and doughnut baffle is the most commonly used baffle The maximum value of baffle spacing is equal to the I.D. of the shell The maximum unsupported tube span is generally about 75 times tube diameter, but is reduced to about 60 times for aluminium, copper & alloys of these The minimum value of baffle spacing is 50 mm ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design Pick out the wrong statement pertaining to the design of a horizontal tube evaporator. Liquor flows inside the tube, while the steam is outside submerging the tube It is suitable for process, in which the final product is a liquor instead of solid Its usual dimensions are: tube dia = 2-3 cms; evaporator body dia = 1-4 metres and evaporator height = 2.5-4 metres It is unsuitable for concentrating those liquids, which form a scale or deposit salt Liquor flows inside the tube, while the steam is outside submerging the tube It is suitable for process, in which the final product is a liquor instead of solid Its usual dimensions are: tube dia = 2-3 cms; evaporator body dia = 1-4 metres and evaporator height = 2.5-4 metres It is unsuitable for concentrating those liquids, which form a scale or deposit salt ANSWER DOWNLOAD EXAMIANS APP
