Pressure drop (Δp) and the superficial gas mass velocity (G) in case of packed absorption tower operating in the preloading range are related as

Δp = G0.5

Δp = G2

Δp = 1/G0.6

Δp = G

Δp = G0.5

Δp = G2

Δp = 1/G0.6

Process Equipment and Plant Design
In a shell and tube heat exchanger for a given heat transfer surface area, smaller diameter tubes are favoured as compared to larger diameter ones ; because the smaller diameter tubes

Are less prone to fouling

Can be fitted into a smaller shell diameter hence the cost of the heat exchanger would be less

None of these

Are easier to clean
