A Stirling cycle is a thermodynamic cycle similar to the Carnot cycle and is defined by the following processes. -> 2: Isothermal expansion -> 3: isochoric cooling -> 4: isothermal heating -> 1: isochoric heating Draw a PV diagram for a Stirling cycle in which 50g of Ar (treated as an ideal gas) is isothermally expanded from 4L to 16L at a temperature of 700K. The sample is then undergoes isochoric cooling to 298K.  The sample is then isothermally compressed to 3L and finally undergoes isochoric heating back to 700K.  Label the states 1 – 4 on the graph.

Solve the following exercise: There is a solution of organic colloids, which is concentrated in water from 12% to 47% in a simple effect evaporator. The water vapor is at a pressure of 150 kPa and the pressure in the evaporator is 13.60 kPa. The feed rate to the evaporator is 12300 kg/h. The overall heat transfer coefficient is taken to be 1600 W/m2 °C. The solution has negligible boiling point elevation.

An Inventor claims to have developed a refrigeration unit which maintains the refrigerated space at -3°C while operating in a room where the temperature is 27°C, and which has a coefficient of performance of 9.5. How do you evaluate his claim?

the following data are for steam power plant:Pressure and temperature of steam at boiler exit and turbine inlet (state2)=30 bar and 300°C. Pressure and quality of steam at turbine exit and condenser inlet (state 3) =20 kpa and 95%.Pressure of saturated water at condenser exit and pump inlet (state 4)=20 kpa.Pressure and temperature of water at pump exit and boiler inlet (state1)=30 bar and 100°C.Steam flow rate =15 kg/s.The heat losses from the body of the turbine =100 kW.Determine the thermal efficiency of the steam power plant

Liquefied natural gas (LNG) is transported in very large tankers, stored as liquid in equilibrium with its vapor at approximately atmospheric pressure. If LNG is essentially pure methane, the storage temperature then is about 111.4 K, the normal boiling point of methane. The enormous amount of cold liquid can in principle serve as a heat sink for an onboard heat engine. Energy discarded to the LNG serves for its vaporization. If the heat source is ambient air at 300 K, and if the efficiency of a heat engine is 61% of its Carnot value, estimate the vaporization rate in moles vaporized per kJ of power output. For methane, AH = 8.206 kJ.mol-¹. The vaporization rate in moles vaporized per kJ of power output is mol-kj1
