For example. 0.5 should be entered as o.50 using the figure below, and then calculate . Please enter both of your answers with two 2.00

Explanation / Answer

1. Critical temperature of methane is 190.6 k

Critical pressure of methane is 45.49 atm

(These values are taken from a particular reference book these may slightly change in your textbook )

Reduced pressure = pressure / critical pressure

= 91.2 / 45.49

= 2.00

Reduced temperature = temperature / critical temperature

= 247.8 / 190.6

= 1.30

2. From the figure given it is evident that the value 1.30 of reduced temperature corresponds to 0.65

Hence z = 0.65
