The dew point is estimated by iterative methods selecting K values at different assumed dew point (usually P or T are known) conditions, using y i/K i, the sum of which must equal 1 for the right (P,T) dew point selection. In each chart the pressure range is from 70 to 7000 kPa (10 to 1000 psia) and the temperature range is from 5 to 260 ✬.
Equilibrium data currently only comes from depriester charts and is assumed.

In these charts, K-values for individual components are plotted as a function of temperature on the x-axis with pressure as a parameter. Download and read online distillation column design i multicomponent systems. (Figures 2.10 and 2.
Sandler in Foundations of Computer Aided Design Vol2, p.83 (AIChE, 1981), may be used as practical and reasonable approximations. One of the earliest K-value charts for light hydrocarbons is presented in reference 1. Farooq/CN3132/Flash Distillation-4 DePriester chart: values for light hydrocarbons This is Figure 2-12 from the text book.

However, in case of light hydrocarbons, the use of K i=y i/x i values taken from DePriester's graphs published by CEP Symposium Series No.7, vol.49, p.41, 1953, re-published in SI units in the CEP vol.74,(4), pp.85-86, April, 1978, or estimated by formulas as recommended by S.I. I must agree with him/her in that programs like the one he/she suggests are available, useful, and sometimes the only chance to reliably estimate VLE conditions for a mixture of chemicals. Experiment with other loan calculators, or explore hundreds of other calculators addressing topics such as math, fitness, health, and many more. Or, simply learn more about loan amortization. If rate of interest is 10.5 per annum, then r 10.00875) n is loan term / tenure / duration in number of months. Free amortization calculator returns monthly payment as well as displaying a schedule, graph, and pie chart breakdown of an amortized loan. r is rate of interest calculated on monthly basis.
To lad圜R, mirchee's approach using computer programs is known to me from another thread. Here's the formula to calculate EMI: where.
