13.20. At one bar, a mixture of mole fractions 0.20, 0.45, 0.25, and 0.10 of n-hexane, n-heptane, iso-heptane, and n-octane, respectively, is prepared. The saturation pressure of each species can be modeled by the equation log10Pvap=c C2/(c3T), where Pap has units of mmHg, T has units of °C, and the constants Ci, C2, and c are given by Table 13.1 Table 13.1 Values of the constants c1, c2, and c3 Species С2 C3 С1 n-hexane 6.87024 1168.72 224.210 n-heptane iso-heptane 6.89385 1264.37 216.636 1236.03 6.87318 219.545 6.90940 1349.82 209.385 n-octane (a) Find the bubble-point temperature of this mixture and the corresponding vapor-phase compositions (b) Find the dew-point temperature and the corresponding liquid-phase compositions (c) At 92 °C, find both the liquid and vapor compositions and the fraction of the system that is vapor

MULTIPLE CHOICE -The answer is one of the options below please solve carefully and circle the correct option Please write clear .

i am confused on where you are getting these equations. is f--- friction? why is it 64/row VD/viscosity?  are there other units at play here?  i am not seeing how they cancel out to become Pa/m

It proposes values for plotting the 6 different viscosity models (Dilatant, Newtonian, Psudoplastic, Plastic Bingham, Psudoplastic Bingham, Dilatant Bingham), all with the help of the formula:All this with the help of matlab. I need help plz i don't realy now how to use this.

A mixture of three components (A, B, and C) enters a separation process.The three components appear in the distillate with variable composi-tion. In contrast, only B and C appear in the bottom. Write a proper set ofmaterial balance equation
