1. Activity 1 questions. From your results in Table 1 of your lab procedure: a. Calculate the rate of fuel consumption of your burner in kg per second. b. Using the energy density of kerosene (closest to our lamp oil fuel) from the Lab 3 Background Appendix, calculate Pfuel, the total heating power generated by your fuel burner. c. Use your measurements of Th and To for your Stirling engine to calculate the maximum thermodynamic efficiency of your engine. d. Use your results from parts 1b. and 1c. to calculate the theoretical maximum mechanical power of your engine. 2. Activity 2 questions. From your results in Table 2 of your lab procedure a. Calculate the gravitational potential energy of your rock at the top of the table relative to the floor. b. Estimate the kinetic energy of the rock as it approached the top of the table top. c. Add your results from parts 2a. and 2b. to estimate the actual average mechanical power of your Stirling engine as it lifted the rock from the floor to the top of the table. d. Use your results from Part 2c. and 1b. to calculate the actual mechanical efficiency of your Stirling engine. e. Compare your result for Part 2d. with your result for Part 1c. What factors account for the difference?Table 1.
