Question

Which of the following statement is not true of the diesel cycle? a. The expansion process is an isentropic process. b. The exhaust process is a constant-volume process. c. The combustion process is a constant-volume process. d. The compression process is an adiabatic process. e. One heat transfer processes is a constant-pressure process. Two water bottles A and B have the same size and shape but are made from different materials (MA and Ma respectively). The same amount of boiling water is put into A and B, and then both bottles are closed with their screw top. After 5 minutes, the temperature of the outside of A is warmer than that of B. We can conclude that a. MA has higher specific heat and the water in A is hotter. b. MA has higher specific heat and the water in B is hotter. c. MA has lower specific heat and the water in A is hotter. d. MA has lower specific heat and the water in B is hotter. e. MA and Ma have the same specific heat and the water in A and B are the same.

Explanation / Answer

The Exhaust process is a constant-volume process - True
The combustion process is a constant-volume process - False , It is a constant-pressure process.
