The Carnot cycle gives the theoretical maximum efficiency of an engine operating between two heat reservoirs. The Carnot cycle is an idealized engine cycle that is thermodynamically reversible. Real systems such as power plants are not reversible, and the entropy of a real material changes with temperature (which is not accounted for by the Carnot cycle). A steam power plant operates closer to a cycle known as the Rankine cycle.

What is the functions of heat power cycle in a steam power plant?
There is no such thing as a heat power cycle in a steam engine.The power stroke, or strokes, result from pressurised steam being let into the cylinder and moving the piston.
How many generators are in the world?
Answer:The La Rance Tidal Power Plant has been in operation since 1966 and has a capacity of 240 MW.South Korea currently (July, 2012) operates the largest tidal power plant in the world.Jiangxia Tidal Power has been in operation since 1985, but only produces 3.2 MW.SeaGen, in Northern Ireland, produces 1.2 MW.In all, there are about 8 so far which produce more than 1 MW, and numerous smaller projects in operation.
When was 3 mile island nuclear power plant built?
Three Mile Island Unit I began commercial operation on September 2, 1974. Unit II (The unit that had the incident in 1979) began commercial operation on December 2, 1978.
What is house load of power plant run parallel with grid and how to calculate it?
House Load of a Power Plant is also known as Auxiliary Power Consumption or Units Used on Works.It is the electrical power needed to drive the pumps and fans that support the operation of the power plant.Typically the power plant metering is set up to measure the electricity produced by the generator at the terminals. A seperate meter will measure the electricity used by the auxiliaries, at the unit transformer.Auxiliary Power Consumption is often expressed as a percentage of Units Generated, so:Aux Power = ( Units Used on Works / Units Generated ) x 100 %% MWh MWhTypical Auxiliary Power Consumption depends on the type of plant:Plant Type%Coal-fired Thermal6.5 - 8.0Open Cycle Gas Turbine2.5 - 3.5Combined Cycle Gas Turbine1.0 - 1.5
What does a reactor do in a nuclear power plant?
The reactor in a nuclear power plant generates heat to flash water to steam, which spins turbines that generate electricity. This is not really any different, in terms of steam cycle1, than a fossil plant. Its just that the source of heat is nuclear fission of (usually) uranium-235 instead of the burning of coal, oil, or natural gas. ----------------------------------------------------------------------------------------------- 1Well, its a little bit different because the nuclear steam supply cycle runs best on a slightly lower pressure and temperature than a fossil fuel plant steam cycle does. Other than that, the steam and generating parts of a nuclear plant are very comparable to a fossil plant.
Difference between rankine and brayton cycle?
Brayton cycle: It is open cycle. Rankine cycle: It's close cycle. Brayton cycle: Mostly used in gas turbine engine. Rankine cycle: Mostly used in power generation plant. Brayton cycle: Resemble less to Carnot cycle. Rankine cycle: Resemble is more to Carnot cycle.
What are limitations in plant expirament?
Limitations in plant experiment entail the lack of one or all of the following: light, water, temperature and nutrients
Operation of a combined cycle power plant?
A combined cycle power plant has multiple thermodynamic cycles. This increases efficiency. For example, a gas turbine can be used to produce electricity, but only about 40% of the heat is actually converted in the process. 60% of the heat is lost, and in a single cycle plant would be considered waste heat. In a combined cycle plant, that waste heat could be used to drive a second, steam turbine to produce more electricity. In such a case, the efficiency could be increased from 40% to nearly 60%. It is possible to go further. The waste heat from the combined cycle electric plant can be used to heat buildings, for instance, increasing overall efficiency to more than 65%. This is called Cogeneration.
What is the plant 's life cycle?
The plants life cycle is when the plant is just a root then it groows and finally it reproduces
What are the stages of life cycle of a flowering plant?
the stages of flowering plant's life cycle starts as a seed then the seedling,mature plant and finally death.
What generation in the plant life cycle has vascular tissue?
Plant
What is the life cycle of a plant from a seed?
The seed germinates and the plant grows larger. Plants do not have a life cycle of several stages.
What happens in the plant cycle?
Well, this is the simplest plant cycle. Here goes.1. Plant grows.2. Plant produces seeds.3. Seeds get planted.4. Plant grows...and so on forever!By PurpleCheese
How would you describe the plant life cycle?
The plant life cycle is divided into two main stages: the sporophyte stage and the gametophyte stage. The sporophyte stage begins when a seed germinates and grows into a mature plant that produces spores. These spores develop into gametophytes, which produce gametes (egg and sperm) that combine to form a new sporophyte plant. This cycle repeats itself to perpetuate plant growth and reproduction.
What is the life cycle of plant that produce seed?
one version of the cycle would be: seed -> seedling -> sapling -> mature plant -> seed
Plant life cycle?
Seed, Sprout, Stem, Flower/Plant
What is a life-cycle dance?
When you create a dance about the life-cycle of an animal or plant.
