What are the differences between a coal power plant and a hydroelectric power plant?
Coal is used in furnaces to heat water in a boiler to superheated (above 100 degrees Celsius) temperatures, and this steam is used to drive a turbine which, in turn, drives an alternator. A hydroelectric plant uses the vertical fall of water to drive a water turbine which drives an alternator.
When electricity leaves the power plant it is measured in what unit?
There are lots of different units for electricity, depending what aspect you want to measure (power, energy, current, voltage, frequency, etc.).For a power plant, some relevant units include: * Volt, for voltage * Ampere, for current * Watt, for power * Hertz, for frequency
What is a depentent variable?
A dependent variable is something that depends on other factors. It is what gets measured and what is affected during an experiment. Without an independent variable there can be no dependent variable.
What do you mean by turbine synchronization?
During a typical power plant startup, all components of the power plant are started slowly. The turbine is first rolled at a slow rpm. Then the rpm is increased gradually to a point where it can match the frequency of the grid. At this point, the turbine can be synchronized with the grid and start outputting electricity into the grid.
What is the difference between nodes and inter node?
The node is the part of the stem of the plant from which leaves, branches, and aerial roots emerge. There are many nodes on a plant stem. The distance between each node is called the inter node.
What is design of a chiller plant?
it is squarish and flattish
What is ikwr in airconditioning chiller plant?
ikwr-input kilowatt rating
What are the release dates for Chiller Cinema - 1999 The Abominable Acid Plant 2-4?
Chiller Cinema - 1999 The Abominable Acid Plant 2-4 was released on: USA: 9 March 2000
What is the definition of chilling plant?
The definition of a plant chiller is a device that lowers the soil temperature to 68 degrees. 68 degrees is the optimal soil temperature for a plant.
What is an independemt variable?
An independent variable is the variable in the experiment that affects the other variable. For example, in an experiment that tests the affect of the amount of fertilizer on plant growth, the amount of fertilizer is the independent variable and the plant growth is the dependent variable. This is because the plant growth DEPENDS on the amount of fertilizer.
In 5th grade science what is a dependent variable?
The dependent variable is what changes. For example, if you are growing a plant, the growth of the plant depends on the amount of light it is given. The growth of the plant is the dependent variable.
What would probably be a variable cost in a soda bottling plant?
examples of variable cost in a soda bottling plant.
Do magnets affect radish plant grow if so what is the control variable?
yes magnets do effect plant growth . the control variable is the plant with magnet.
A sentence for independent variable?
i am testing a independent variable for my plant it was worth
What best describes the relationship between a dependent variable and an independent variable in a scientific investigation?
The independent variable is what you are changing in the experiment to get varied results. The dependent variable is the result of what you have changed. So the dependent variable depends on the independent variable. For example, if you are experimenting with the effect of water on height of a plant, the different amounts of water that you give the plant is the independent variable. The height of the plant that you measure as the result of the water is the dependent variable.
Procedure to switch on chiller plant?
If your chiller has the option of controlling the pumps then the start command should go to the chiller. The start command could be from a time clock or BAS. The chiller then starts condenser and cooler pumps then starts the compressor. It is important to allow the chiller to control the pumps to protect the tubes from freezing. The old way was often to turn on the chilled water pump then the chilled water flow switch would start the chiller. Check the installation, operation and or maintenance books for your specific machine, if you don't have them get them! many can be downloaded. Go with the manufactures recommended procedures to CYA!!
What is the dependent variable in a science experiment?
The dependent variable is the effect of an independent variable. For example, if a science experiment is done with plant growth under a certain amount of light, the height of the plant is the dependent variable because it depends on the amount of light.
