Methane is throttled from a saturated liquid at 152.9 K (Stream 1) to 0.464 MPa (Stream 2) where it is a saturated mixture. Assuming methane has a constant Cp of 2.2537 kJ/(kg K), use the Generalized Charts provided on eClass to determine:a) the pressure of Stream 1 (in MPa) and the temperature of Stream 2 (in K)b) the quality of the exit stream in %c) the entropy generation per kg being throttled, in kJ/(kg K)d) the specific volume of the methane in Stream 1, in m3/kgNote: Use the Generalized Charts provided on eClass to solve this problem. You will not be able to use the Charts in the textbook to solve this problem since they do not cover all the regions of the phase diagram.
