1. Consider a medium in which the heat conduction equation is given by i. ii. iii. iv. v. Answer the following questions for each case: (a) Is the heat transfer steady or transient? (b) Is heat transfer one-, two-, or three-dimensional? (c) Is there heat generation in the medium? (d) Is the thermal conductivity of the medium constant or variable? Solutions i. ( a ) Heat transfer is transient, ( b ) it is two-dimensional, ( c ) there is no heat generation, and ( d ) the thermal conductivity is constant. ii. ( a ) Heat transfer is steady, ( b ) it is two-dimensional, ( c ) there is heat generation, and ( d ) the thermal conductivity is variable. iii. ( a ) Heat transfer is steady, ( b ) it is one-dimensional, ( c ) there is heat generation, and ( d ) the thermal conductivity is variable. iv. ( a ) Heat transfer is transient, ( b ) it is one-dimensional, ( c ) there is no heat generation, and ( d ) the thermal conductivity is constant. v. ( a ) Heat transfer is steady, ( b ) it is one-dimensional, ( c ) there is no heat generation, and ( d ) the thermal conductivity is constant.

### What students are saying

• 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.
