An engineer is working with a Carnot engine that has an unknown cold-reservoir temperature (TC) but a known and controllable hot-reservoir temperature (TH). He measures the efficiency of the engine as a function of the hot-reservoir temperature and produces the following data set:
TH (K) | е |
300 | 0.133 |
370 | 0.298 |
425 | 0.390 |
483 | 0.461 |
535 | 0.513 |
Produce a linearized plot of the engine efficiency as a function of the hot-reservoir temperature. Using a “best fit” to the data, determine the cold-reservoir temperature.

- A Carnot engine has an efficiency of 0.60. When the temperature of its cold reservoir the efficiency drops to 0.55. If initially Tc=27, determine (a) the constant value of Th and (b) the final value of Tc.arrow_forwardA thermal engine produces 4 MJ of electrical energy while operating between two thermal baths of different temperatures. The working substance of the engine discharges 5 MJ of heat to the cold temperature bath. What is the efficiency of the engine?arrow_forwardAt point A in a Carnot cycle, 2.34 mol of a monatomic ideal gas has a pressure of 1 4000 kPa, a volume of 10.0 L, and a temperature of 720 K. The gas expands isothermally to point B and then expands adiabatically to point C, where its volume is 24.0 L. An isothermal compression brings it to point D, where its volume is 15.0 L. An adiabatic process returns the gas to point A. (a) Determine all the unknown pressures, volumes, and temperatures as you f ill in the following table: (b) Find the energy added by heat, the work done by the engine, and the change in internal energy for each of the steps A B, B C, C D, and D A (c) Calculate the efficiency Wnet/|Qk|. (d) Show that the efficiency is equal to 1 - TC/TA, the Carnot efficiency.arrow_forward
