Homework Answers
Limitations of the Logarithmic Mean Temperature difference(LMTD) method are:-
1. The fluids have constant Specific heat Capacity, so the rate of change of temperature is proportional to the temperature difference.
2. The overall Heat Transfer Coefficient (U) will be constant. so it will not be a function of temperature.
3. The LMTD method cannot be used in Transient situations.
4. The flow should be steady.
5. There should not be any phase change during heat Transfer.
6. The change in Kinetic energy and Potential Energy is neglected.

(1) Use finite the difference method to solve for the temperature profile given by the equation below. The thin rod is one (1) meter long. The temperature on the left end is 100 and 0 on the right end. Set up the problem for three internal nodes (unknowns). Set up the augmented matrix for Gauss elimination solution (do not solve). Roughly sketch the five T values (including BC's).

a. What is the difference between coupon rate and yield to maturity? How do you use the coupon rate to calculate the periodic payment received from a bond? b. What is the price of a bond that is currently trading at a yield of 10% and has a face value of $1,000? This bond still has exactly 5 years to maturity. This bond pays semi-annual coupon at an annual rate of 8% (i.e., each coupon is 4%). Show how you...

What does it mean to 'solve a polynomial inequality'? What do you look for in the original problem to know that it is indeed a polynomial inequality? What cues do you look for to help you get the solution process started? What might the solutions to the polynomial inequality look like? Include a specific example of at least one polynomial inequality. You may state the polynomial inequality only, no need to solve it. For example, "I know ... is a...

How do I solve?
When you blow across the top of a soda bottle, it acts like a closed pipe with a fundamental frequency of 495 Hz. If you pour 0.030 m of water into the bottle, shortening the air cavity, what is the new fundamental frequency? (Hint: Find the original length.)

Quick question, I want to know how to convert decimal numbers to binary number, when i have a number like "472" i can convert that, but i get confused when i have something like "472.45" , does this kind of situation just follow the same rule, I mean, can I just convert 472 first, then put a point and convert 45 as well? or not, please help. And, what happen when I have something like " -0.1" for example? Thanks!
