The amine solution has a specific gravity of 1.02 and a viscosity at the operating temperature of $1.5 \mathrm{cP}$. If the gas must leave the column at $25 \mathrm{psig}$ and a flow rate of $10,000 \mathrm{scfm}$, determine

(a) The flow rate of the liquid (in gpm) that is $50 %$ of that at which flooding would occur

(b) The horsepower that would be required for the blower to move the gas through the column, if the blower is $80 %$ efficient
