The working gas of a thermodynamic cycle is a diatomic gas (assume constant specific heats.) The gas originallystarts at 100kPa, 4m ³ and 27° C. It undergoes a four-step process---• Process A-B: The gas is compressed at constant temperature to one-quarter of its original volume.• Process B-C: The volume of the gas is then doubled at constant pressure.• Process C-D: The gas then undergoes an adiabatic expansion.• Process D-A: The gas then undergoes a constant volume process back to its original statea) Make a table of the temperature, pressure, volume, internal energy, enthalpy, entropy and quality factor (T,P, V, U, H & S) at the start of each process.b) Make a table of the change in internal energy, heat flow, work done, change in enthalpy, and change inentropy (AU, Q, W, AH & AS) during each leg of the cycle.c) Draw well-labelled P-V & T-S diagrams (indicating lines of constant temperature, heat flow, work, etc.)d) Calculate the thermal efficiency of the cycle.

The objective of the question is to analyze a thermodynamic cycle involving a diatomic gas…

(2) Describe briefly why the following statements are wrong. (a) "Hot cup of coffee becoming cold spontaneously is an entropy-decreasing process. So the law of entropy increase can be violated." (b) “Air conditioners require bulky external unit, exhausting heat to outside. With the technology constantly advancing, external unit will be eliminated in the future."
Example 15.18. Steam at a pressure of 15 bar and 250°C is expanded through a turbine at first to a pressure of 4 bar. It is then reheated at constant pressure to the initial temperature of 250°C and is finally expanded to 0.1 bar. Using Mollier chart, estimate the work done per kg of steam flowing through the turbine and amount of heat supplied during the process of reheat. Compare the work output when the expansion is direct from 15 bar to 0.1 bar without any reheat. Assume all expansion processes to be isentropic.
A water pump is to be purchased for a mechanical boiler system. The cost is 20,000 TL with a depreciation rate of 10% for a service life of 10 years. Determine the depreciation of the compressor for the second year using the declining-balance depreciation method and find the correct answer stated below.

A steam turbine drives an air compressor-all power produced by the turbine is sent to the compressor; there is no extra power produced. Steady-state operating data are provided on the figure. Assume the ideal gas model for air, and ignore stray heat transfer and kinetic and potential energy effects.

A good oil well in the Persian Gulf produces about 100,000 bbl of oil per day. What mass flow rate of steam from a geothermal well located at the Larderello field in north- ern Italy would be required to provide the same rate of energy production? Are there any practical limitations to achieving this production rate? The Larderello field produces saturated steam at about 20 bar, 212.4°C. Assume a typical Larderello well is about 28 cm in diameter and is about 2,500 m deep. The enthalpy of vaporization is 1,890.7 kJ/kg at 20 bar. Assume an average liquid phase heat capacity for water of 4,100 J/kg K. Note that the energy content of a bbl of oil, which is about 5 million Btu, is referenced to its heat of combustion at 25°C.
Hi I'm looking for an explanation of WHY h3 = h4 =h9? Basically why states 3 and 4 are also saturated liquid alongside state 9? how do i understand it using the information given in the question attatched thank you.

The figure shows a reversible cycle through which 1.00 mole of a monatomic ideal gas is taken. Process bc is an adiabatic expansion, with pb = 5.80 atm and Vb = 1.00 x 10-3 m3. For the cycle, find (a) the energy added to the gas as heat, (b) the energy leaving the gas as heat, (c) the net work done by the gas, and (d) the efficiency of the cycle.
With an ideal gas as the working substance, what are the steps of the Carnot cycle?
