Question

Methane at 10 MPa and 200℃ is heated at constant pressure until its volume has increased by 75%. Determine the final temperature using : (a) Van de Waals constitutive eq. (b) Redlich Kwong constitutive eq. (c) Lee and Kesler correlation for compressibility factor (d)Ideal gas eq. Make a comment about which result is more reliable.

Expert Solution
Given Data

"Since you have posted a question with multiple sub-parts, we will solve the first three subparts for you. To get the remaining sub-part solved please repost the complete question and mention the sub-parts to be solved"

Initial Pressure, P1 = 10 MPa

Initial temperature, T1 = 200 C

Final pressure, P2 = P1

V1V2=11.75

It is asked to find the final temperature by using (a) Van de Waals constitutive eq. (b) Redlich Kwong constitutive eq. (c) Lee and Kesler correlation for compressibility factor
