Carnot engine operating

The oceans in the tropics have substantial surface-to-deep-water temperature gradients. Depending on location, relatively constant temperature differences of 15 to 25oC can obtain for depths of 500 to 1.000 m. This provides the opportunity for using cold (deep) water as a heat sink and warm (surface) water as a heal source for a power cycle. The technology is known as "OTEC (Ocean Thermal Energy Conversion).(a) Consider a location where the surface temperature is 27oC and the temperature at a depth...

A Carnot engine uses air as the working substance, receives heat at a temperature of 315oC, and rejects it at 65oC. The maximum possible cycle pressure is 6.0MPa and the minimum volume is 0.95 liters. When heat is added, the volume increases by 250%. Determine the pressure and volume at each state in the cycle.

Why is it that thermal radiation of a black body usually described by a spectral distribution...

Why is it that thermal radiation of a black body usually described by a spectral distribution function rather than an intensity vs frequency curve? I have a vague explanation for this: Any measured intensity of radiation will contain a spectrum of frequencies which are impossible to separate (even with a very good spectrometer, one can only measure the intensity of an interval). So it is practically impossible to assign a particular intensity to a particular frequency. Is my reasoning correct?

A Carnot heat engine within a piston cylinder has 10 kg of air as the working fluid and operates between 1000 K and 350 K. During the heat addition process the pressure changes by a factor of 2.5. The volume at the end of the isentropic compression process is 5m^3. Determine the pressure at each state in kPa and the net heat of the cue in KJ assuming Constant Heats at 300 K. Draw a P-v and T-s diagram

How does black body radiation related to quantum mechanics in the earliest stage?

Describe in your own words how the theory of black-body radiation was formulated by Rayleigh and...

Describe in your own words how the theory of black-body radiation was formulated by Rayleigh and Jeans. Be sure to include how the density of the modes of radiation and the Boltzmann distribution were incorporated into their description. Discuss the shortcomings of the Rayleigh-Jean theory. Describe how Planck modified the theory to make it successful. Your answer should not exceed 2 handwritten pages. Your answer should be mostly descriptive, rather than a detailed mathematical derivation. You may find that including...

Carnot Engine questions: What was the full name of the man who imagine the first Carnot Engine? What thermodynamic theory did he use to calculate its efficiency? Describe a Carnot engine, in terms of thermodynamic processes. What does Carnot's Theorem say about the efficiency of a Carnot engine operating between two absolute temperatures? What does Carnot's Theorem say about the efficiency of a reversible engine which is not a Carnot engine operating between two absolute temperatures? What does Carnot's Theorem...

Professor Modyn wants to power his refrigerator with a heat engine. A Carnot heat engine receives heat from a reservoir at 493.0°C at a rate of 767 kJ/min and rejects heat to the ambient air at 29.1°C. The entire work output of the heat engine is used to drive a refrigerator that removes heat from the refrigerated space at -3.23°C and transfers it to the same ambient air at 29.1°C. Note: The IUPAC sign conversion for work is used. Work...

An engine operates in a Carnot cycle. At point A in the cycle, 2.34 mol of a monatomic ideal gas has a pressure of 1,400 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....
