C HEMICAL E NGINEERING 132A Professor Todd Squires Spring Quarter, 2007 Homework 4 Due Friday, May 18 Problem 1. A bar is located between x = 0 and x = 2, and has an inital temperature profile T 0 ( x ) = 0 , 0 x < 1 / 2 (1) T 0 ( x ) = 100 , 1 / 2 x 3 / 2 (2) T 0 ( x ) = 0 , 3 / 2 x 2 (3) At t = 0, the rod is placed between two ice blocks to maintain T = 0 at both ends ( x = 0 and x = 2), for all time. Solve the heat equation ∂T ∂t = k 2 T ∂x 2 (4) to find the evolution of the temperature. Show all steps – the separable solution, Fourier Sine Series, etc. As t → ∞ , what happens to the temperature in the bar? Problem 2. Consider the same problem as above, except now the ends are

How is this di³erent than in Problem 1, and why? Problems 3a-d. p503, probs 1, 2, 5, 8 Problems 4a-d. p503, probs. 10, 16, 21, 27 (these analyze your solutions above; not so involved) Problem 5a-c. p504, probs 32, 33, 36.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
