A Carnot refrigeration cycle is used as a reference to estimate the energy needed in an attempt to reduce the temperature of a laboratory sample to absolute zero. Suppose you want to remove 0.01 J of energy from the sample that is at 2x10-6K. If the high temperature is 20°C, the heat required is 982.05x10-5J. Analyzing these considerations, calculate the increase in laboratory entropy and the decrease in entropy in the sample.
A medium size power station is used to produce 30 MW net power for a refinery. The station uses steam as the operating fluid and operates according to the Carnot cycle between the pressure limits of 0.4 bar and 35 bar.

In the condenser of the power plant, Ammonia is isobarically condensed to saturated liquid state with 615.2kPa and x = 0.9, the mass flow rate is 4 t/h. The heat rejected from the condensing ammonia is added to heat water, which is heated from 277K to 281K. What is the mass flow rate of water in t/h. Also sketch the T-s and P-v diagrams.
Consider an engine operating on the following cycle using 4 moles of neon as the working fluid. Starting at a pressure of 5 atm and a volume of 2m3, the gas expands isothermally to a volume of 3m3, then is compressed isobarically back to 2m3, and finally returns isochorically to the initial state. What is the efficiency of this engine?
