Ten thousand kg per hour of a liquor with 10% solids is fed at 294 k to the 1" effect of a double-effect unit. liquor with 50% solids is to be widthrawn from the second effect, which is at a pressure of 0.13 bar. the liquor will be assumed to have a specific heat of 4.18 kj/kg-k and to have no bpr. saturated steam at 205 kn/m2 is fed to the heating element of the first effect. if both units are to have equal areas, estimate the steam consumption and the areas of each effect. assume heat transfer coefficients of 3.1, and 2.0 kw/m2-k for the first and second effects, respectively
