What is the use of condenser in Rankine Cycle?

What is the use of condenser in Rankine Cycle?

A condenser is used to convert the steam from the exit of the turbine to saturated liquid. This is done so that we can use a pump to pressurize the liquid. There is no mechanical device till date which can work on steam+liquid mixture. So we have to use a pump or a compressor to increase the pressure.

What is the Rankine cycle used for?

Rankine cycle, in heat engines, ideal cyclical sequence of changes of pressure and temperature of a fluid, such as water, used in an engine, such as a steam engine. It is used as a thermodynamic standard for rating the performance of steam power plants.

What is critical point in Rankine Cycle?

The critical point is where the temper- ature and pressure are such that the fluid is no longer classified exclusive- ly as liquid or gas. It is thought of as a fluid above the critical point. The criti- cal point for water is slightly above 3200 psi.

How many processs are there in Rankine Cycle?

four processes

How is Rankine calculated?

absolute temperature scale Fahrenheit scale is called the Rankine (°R) scale. These scales are related by the equations K = °C + 273.15, °R = °F + 459.67, and °R = 1.8 K. Zero in both the Kelvin and Rankine scales is at absolute zero.

What is the formula to calculate enthalpy?

If you want to calculate the enthalpy change from the enthalpy formula:

1. Begin with determining your substance’s change in volume.
2. Find the change in the internal energy of the substance.
3. Measure the pressure of the surroundings.
4. Input all of these values to the equation ΔH = ΔQ + p * ΔV to obtain the change in enthalpy:

Which has highest entropy?

Hydrogen

What is entropy and probability?

Entropy measures the expected (i.e., average) amount of information conveyed by identifying the outcome of a random trial. This implies that casting a die has higher entropy than tossing a coin because each outcome of a die toss has smaller probability (about ) than each outcome of a coin toss ( ).

What does an entropy of 1 mean?

This is considered a high entropy , a high level of disorder ( meaning low level of purity). Entropy is measured between 0 and 1. (Depending on the number of classes in your dataset, entropy can be greater than 1 but it means the same thing , a very high level of disorder.

Can entropy be reversed?

Entropy in closed systems cannot be reversed globally with overwhelming probability, but it can be reversed locally as long as it is possible to put the entropy somewhere else. “the second law of thermodynamics says that entropy always increases with time.”

What happens if entropy is reversed?

There are more ways for random energy to enter the system, than there are for a very specific form of energy to enter the system to maintain the ordered (lower entropy) state. You can never win. Reversing entropy would mean going back in time, so a short answer, no. However if you mean decreasing then you could.

Is Absolute Zero Possible?

Absolute zero, technically known as zero kelvins, equals −273.15 degrees Celsius, or -459.67 Fahrenheit, and marks the spot on the thermometer where a system reaches its lowest possible energy, or thermal motion. There’s a catch, though: absolute zero is impossible to reach.
