MAE 334 Lab 3 approach. Check your time constant estimate by plotting Excel simulation results for the differential equation on top of the cool down data. Equation (11) of the “Further Background” section can then be used to calculate H. An Overall Simulation At this point, you have an estimate for the calorimeter time constant and the overall convection factor H. The mechanical power input for a 125 rpm input to the calorimeter can also be determined. With this information and knowing that dT/dt = 0 at steady state, use Equation (6) to determine the final temperature of the calorimeter with the 125 rpm input. With these results and the standard first order solution f T τ t lab f f e T T T T = ) ( Use Excel to simulate and plot the expected transient behavior of the calorimeter starting at the lab temperature if it were subject to the 125 rpm mechanical input until a steady temperature was reached. Report In your Summary , briefly describe your lab experiment and results. Be sure that your Results

### 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.
