Process Equipment and Plant Design Pick out the wrong statement about the design of seive plate column and the bubble cap column. Weir height in case of a bubble cap plate ranges from 50 to 150 mm and is higher than the seive plate The downcomer design and the residence time in the downcomer is almost same for seive plate and bubble cap columns Weir height for a bubble cap plate column is the same as that for a seive plate column Weir length for a bubble cap plate is the same as that for the seive plate Weir height in case of a bubble cap plate ranges from 50 to 150 mm and is higher than the seive plate The downcomer design and the residence time in the downcomer is almost same for seive plate and bubble cap columns Weir height for a bubble cap plate column is the same as that for a seive plate column Weir length for a bubble cap plate is the same as that for the seive plate ANSWER DOWNLOAD EXAMIANS APP

Process Equipment and Plant Design The centre to centre distance between two consecutive baffles in a shell and tube heat exchanger is called the baffle pitch or baffle spacing, which is more than 1/5th the I.D. of the shell. Which of the following is not a function of the baffles? To increase the tube side heat transfer co-efficient by inducing turbulence To increase the residence time of shell side fluid To provide support to the tube bundle To reduce the induced vibration in the tubes To increase the tube side heat transfer co-efficient by inducing turbulence To increase the residence time of shell side fluid To provide support to the tube bundle To reduce the induced vibration in the tubes ANSWER DOWNLOAD EXAMIANS APP
