Find rate of heat transfer and rate of entropy generation

Question

Problem

1. One kmol/s of saturated liquid methane, CH₄, at 1 MPa and 2 kmol/s of ethane, C₂H₆, at 250^oC, 1 MPa are fed to a mixing chamber, with the resultant mixture exiting at 50^oC, 1 MPa. Assume that Kay's rule applies to the mixture and determine the heat transfer in the process.

2. Saturated liquid ethane at T₁ = 14^oC is throttled into a steady-flow mixing chamber at the rate of 0.25 kmol/s. Argon gas at T₂ = 25^oC, 800 kPa, enters the chamber at the rate 0.75 kmol/s. Heat is transferred to the chamber from a constant temperature source at 150^oC at a rate such that a gas mixture exits the chamber at T₃ = 120^oC, 800 kPa. Find the rate of heat transfer and the rate of entropy generation.

The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
