Repeat problem 11-3-21 with the hot gas argon replaced by neon (all other conditions remaining the same).
Question:
Problem 11-3-21
Helium at 200 kPa, 20oC is heated by mixing it with argon at 200 kPa, 500oC in an adiabatic chamber. Helium enters the chamber at 2 kg/s and argon at 0.5 kg/s. If the mixture leaves at 200 kPa, determine
(a) The temperature (T2) at the exit
(b) The rate of entropy generation (Sgen) due to mixing.
(c) Explain the change in entropy generation rate (Sgen).

I consider myself to have excellent interpersonal and assessment skills with strong teaching presentation verbal and written communication
I love tutoring. I love doing it. I find it intrinsically satisfying to see the light come on in a student's eyes.
My first math lesson that I taught was when I was 5. My neighbor, still in diapers, kept skipping 4 when counting from 1 to 10. I worked with him until he could get all 10 numbers in a row, and match them up with his fingers.
My students drastically improve under my tutelage, generally seeing a two grade level improvement (F to C, C to A, for example), and all of them get a much clearer understanding!
I am committed to helping my students get the top grades no matter the cost. I will take extra hours with you, repeat myself a thousand times if I have to and guide you to the best of my ability until you understand the concept that I'm teaching you.
