Q1:

L/mGis the expression for

A absorption factor

B Brinkman number

C slope of operating line in absorber

D slope of operating line in stripper.

ANS:A - absorption factor

The expression ðŋ/𝑚𝐚L/mG represents the slope of the operating line in an absorber. In absorption processes, the operating line represents the relationship between the liquid flow rate (L) and the gas flow rate (G) at each stage of the absorber. The slope of this operating line is an important parameter that influences the efficiency of the absorption process. The ratio ðŋ/𝑚𝐚L/mG (where 𝑚m is the slope of equilibrium curve) is used to characterize this slope, and it helps in determining the optimal operating conditions for the absorber.
