Pick out the wrong statement pertaining to the design of the bubble cap tray of a distillation column to give stable operation and even vapour distribution.

None of these
The dimensionless ratio of liquid gradient to pressure drop head caused by the bubble cap assembly should be less than 0.4
The pressure drop due to the caps & slots and the static submergence should be as high as practicable for reasonable operation
Tendency towards stable operation is increased by increasing the skirt clearance of the caps, lowering the rate of liquid flow per unit plate width or increasing the spacing between the caps

High pressure fluid in a shell and tube heat exchanger should preferably be routed through the

Shell side for large overall heat transfer co-efficient
Shell side for smaller total pressure drop
Tubes to avoid the expansion of high pressure shell construction
Shell side, if the flow is counter-current and tube side if the flow is co-current

Smoker's equation for the calculation of number of equilibrium stages in a continuous binary distillation column is used, when the

Feed is not at its bubble point
Relative volatility is close to one (e.g., separation of close boiling isomers)
Number of equilibrium stages required is likely to be very small
Number of equilibrium stages in only stripping section is to be calculated
