A liquid mixture containing 0.45 mol fraction of heptane and 0.55 mole fraction ethyl benzene is fed as saturated vapor to a dis

tillation column at a flow rate of 200 kgmol/h for product separation. The distillation operates at 1 atm (absolute). The recovery of heptane (to the distillate product) is 95% and the required heptane purity in the distillate is 0.98 (mole fraction). Calculate the following:
a. The distillate and bottom flowrates
b. The minimum reflux ratio
c. The minimum number of stages
d. The number of stages at a reflux ratio of 1.5Rmin

1.The moist unit weights and degrees of saturation of a soil are given: moist unit weight (1) = 16.62 kN/m^3, degree of saturati
alexandr1967 [171]

Answer:

Gs = 2.647

e = 0.7986

Explanation:

We know that moist unit weight of soil is given as

\gamma_m \ or\ bulk\ density = \frac{(Gs+Se)\times \gamma_w}{(1+e)}

where,  \gamma_m = moist unit weight of the soil

Gs = specific gravity of the soil

S = degree of saturation

e = void ratio

\gamma_w = unit weight of water = 9.81 kN/m3

From data given we know that:

At 50% saturation,\gamma_m = 16.62 kN/m3

puttng all value to get Gs value;

16.62= \frac{(Gs+0.5*e)\timees 9.81}{(1+e)}

Gs - 1.194*e = 1.694 .........(1)

for saturaion 75%, unit weight = 17.71 KN/m3

17.71 = \frac{(Gs+0.75*e)\times 9.81}{(1+e)}

Gs - 1.055*e = 1.805 .........(2)

solving both  equations (1) and (2), we obtained;

Gs = 2.647

e = 0.7986
