Process Equipment and Plant Design Pick out the wrong statement pertaining to a shell and tube heat exchanger. The maximum value of baffle spacing is equal to the I.D. of the shell The minimum value of baffle spacing is 50 mm 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 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 minimum value of baffle spacing is 50 mm 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 Disk and doughnut baffle is the most commonly used baffle ANSWER DOWNLOAD EXAMIANS APP
