Why the stress value is taken on y axis not on x axis as it is the cause and strain is effect so why not it is taken on x axis and strain on y axis?
in any graph on horizontal axis we keep the independent variable and on vertical axis the dependent variable. similarly in stress strain diagram the strain is independent variable and stress is dependent variable so due to this reason strain is kept on x-axis and stress is kept on y-axis.
WHY IS 24 a more convenient choise for the number of hours in a day than 23 or 25?
because, Our earth completes rotation on own axis in 24 hours. So it is kept as length of 1 day
Where is the perfect meter kept?
Its kept in a museum in Paris, inside a glass case with the temperature inside the case kept the constant.
What means the variable that must be kept constant?
What variables must be kept constant
What is a controlled variable in experimental psychology?
A controlled variable is the thing that is kept consistent in between trials of doing an experiment. e.g: time is kept the same or kept consistent...
What is controlled and uncontrolled extraction in double extraction steam turbine?
The extraction of steam can either be controlled or uncontrolled. In an uncontrolled extraction the pressure of the extracted steam will decrease with an increase in extraction flow from the turbine. In a controlled extraction the extraction pressure is kept constant as extraction flow is increased or decreased.
Why steam turbine speed is kept constant in power plants?
Well, the steam turbbine is most likely connected to an A/C generator which gives off the same frequency as the grid, so by running the turbine on a fixed frequency you don't have to condition the electricity before it can be released onto the grid.
What is inclination of steam drum?
Boiler drum inclination is kept at 1:50 with the horizontal i.e. around 6 to 8 degrees.

Why is the water that is used to cool the reactor vessel of a nuclear power plant is kept separate from the water that is heated to produce steam for the turbine generators?
To reduce radioactive contamination.
Why horizontal vessel is kept in low pressure?
because horizontal vessels can't kept a high presssure
Why the water that is used to cool the reactor vessel of a nuclear power plant is kept separate from the water that is heated to produce steam for the turbine generators?
Not quite sure what you are referring to. In the reactor primary circuit, there are of course the main circulating feed pumps that transfer the reactor heat output to the steam raising units (PWR) or the turbine (BWR). In the event of a loss of the main power outlet line, the plant will safely shutdown, reactor and turbine/generator together, and these feed pumps will lose their electrical supply. But there is decay heat produced from the reactor and it must be kept cool to prevent fuel damage. Therefore emergency feed pumps are provided which can be run from back up diesel generators. In the PWR there is in addition the secondary loop which takes water from the turbine condenser and passes it through the steam raising units. Both types of reactor also have the turbine condenser cooling circuit which takes water from either a lake, river, or the ocean, or from air flow cooling towers, to condense the steam at the turbine back end.
How do you generate electricty?
The primary means of producing electricity from heat involves heating water until it becomes steam, this steam is kept under pressure so that its volume remains the same while it continues to gain the energy from the heat. Once the steam has absorbed as much energy as we can give it, we allow it to expand into pipes, releasing the energy we put in as it does. That heat energy is transfered to rotational motion as the steam expands and pushes the blades of a turbine. The axle of the turbine is in turn connected to a generator which turns rotational motion into electricity. weather the heat is generated by nuclear reactions, coal, or whatever else you like is irrelevant.

How is a Pressurized Water Reactor different from a Boiling Water Reactor?
In a PWR the pressure in the reactor primary circuit is kept high enough to prevent boiling, and heat is transferred to a secondary circuit at a lower pressure where steam is produced for the turbine. In a BWR a proportion of the water passing into the reactor is allowed to boil off feeding directly to the turbine. Otherwise, the reactor core itself is very similar.
Why is the axis of Uranus tilted?
meteroits kept hitting it so it kinda tilted.
How do external combustion engines produce mechanical energy?
"External combustion engine" almost always means a steam engine. There are two kinds. Reciprocating steam engines have a boiler to make steam, a piston assembly for the steam to act against, and a flywheel for the piston assembly to turn. The first steam engines were "single acting" engines. You introduce steam into the piston assembly. When it reaches the bottom of its travel, the rotating flywheel forces the piston back to the top. This is how single-cylinder internal combustion engines work. That's not efficient because you rely on mechanical inertia to make the engine work, so someone invented the "double acting" engine. The piston assembly has two pistons in it. When the piston on the left side reaches the bottom of its stroke the one on the right has reached the top of its, and a valve switches the steam from the left piston to the right one. This is far more efficient, and it's how any internal combustion engine with more than one cylinder works. To get useful work out of this thing, you put a big drive belt around the flywheel. Steam turbines are a lot like jet engines, except that jet engines don't have boilers. There are two kinds of turbine wheels, and every steam turbine contains both types. One kind has blades that you shoot steam against. The other kind has nozzles that steam shoots out of. The guy who invented this motor knew the first wheel wouldn't use all the energy in the steam, so he captured the steam used on the first wheel to drive a second, and he kept going until all the usable energy had been extracted from the steam. The shaft of the steam turbine directly drives the load.
