A distillation column with two feeds is separating ethanol from water. The first feed is $60wt\%$ ethanol, has a total flow rate of $1000k\frac{g}{h},$ and is a mix of liquid and vapor at $81C.$ The second feed is $10wt\%$ ethanol, has a total flow rate of $500k\frac{g}{h},$ and is liquid at $20C.$ Bottoms product is $0\mathrm{.}01wt\%$ ethanol, and distillate product is $85wt\%$ ethanol. The column operates at $1k\frac{g}{c}m2$ and is adiabatic. The column has a partial reboiler, which acts as an equilibrium contact, and a total condenser. The distillate and reflux are saturated liquids. Find B and D in $k\frac{g}{h},$ and find $Qc$ and $QR$ in kca$\frac{l}{h}.$ Use data supplied.

Boil$-$up ratio, is $\frac{V}{B}=2\mathrm{.}5($mass units$).$
