Process Equipment and Plant Design Pick out the wrong statement about the design of seive plate column and the bubble cap column. 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 The downcomer design and the residence time in the downcomer is almost same for seive plate and bubble cap columns Weir height in case of a bubble cap plate ranges from 50 to 150 mm and is higher than the seive plate 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 The downcomer design and the residence time in the downcomer is almost same for seive plate and bubble cap columns Weir height in case of a bubble cap plate ranges from 50 to 150 mm and is higher than the seive plate ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design High pressure fluid in a shell and tube heat exchanger should preferably be routed through the Tubes to avoid the expansion of high pressure shell construction Shell side for smaller total pressure drop Shell side, if the flow is counter-current and tube side if the flow is co-current Shell side for large overall heat transfer co-efficient Tubes to avoid the expansion of high pressure shell construction Shell side for smaller total pressure drop Shell side, if the flow is counter-current and tube side if the flow is co-current Shell side for large overall heat transfer co-efficient ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design In a shell and tube heat exchanger, the overall heat transfer co-efficient is proportional to the tube side (volumetric flow rate)0.8. This is valid, only when the ratio of the tube side film resistance to the total resistance is almost equal to 20.8 ∞ 2 1 20.8 ∞ 2 1 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 provide support to the tube bundle To increase the tube side heat transfer co-efficient by inducing turbulence To reduce the induced vibration in the tubes To increase the residence time of shell side fluid To provide support to the tube bundle To increase the tube side heat transfer co-efficient by inducing turbulence To reduce the induced vibration in the tubes To increase the residence time of shell side fluid ANSWER DOWNLOAD EXAMIANS APP
