What are importance of platform balance?
Platform balance is a device that weights object that has a flat plate mounted above a balance beam. It is used to weight heavy objects, it also gives the exact weight of an object that is being weight and it allows large weight to be accommodated in a small space.
During the laser printing process what determines when the toner sticks to the drum and when it does not stick to drum?
Laser printers work by placing toner on an elecrically charged rotating drum and then depositing the toner on paper as the paper moves through the system at the same speed as the drum is turning. The negatively charged toner is more negative than the -100 V charge on the drum surface but less negative than the -600 V. The toner is attracted to the -100 V area of the drum because the -100 is more positive than the toner is; the toner is repelled from the -600 V part of the drum because it is more negative than the toner is.The electric charge at each point on the drum surface. This in turn is determined by the amount of light received by each point on the drum. The process begins by charging the entire drum surface. The image to be copied is then projected onto the drum.
What is a ledoux bell manometer?
A ledoux bell manometer uses a shaped "bell" suspended in mercury to mechanically extact a linear output from a square root flow signal. Seldom used any longer they were popular when pneumatic flowmeters were the standard. Often used on boiler control the advantage of a linear flow signal was that the material balance between drum level, gas flow and steam flow was easy to calculate using linear signals. The shape of the "ledeoux" bell was critical to the accuracy of extracting the square root.
Micro switches are used for what purpose?
Micro switches are small snap-action switches generally used in some type of electronic circuit for some type of repetitive motion. In an air conditioning unit, a micro switch might send a signal to turn the compressor on or off when a room reaches a certain temperature.
Explain the important features of high pressure boilers used in power plants?
1) Methods of circulation of water and Steam 2) Arrangement of tubing and boiler drum 3) Methods of superheating the steam 4) water softening plant
Which compressor is used for supercharging of ic engines?
Centrifugal compressor
Which compressor is mostly used for supercharging of ic engines?
Centrifugal compressor
Which compressor is mostly used for the supercharging of IC engines?
Centrifugal compressor
What is the air compressor in a car used for?
The air conditioning compressor pressurizes the refrigerant sending it through a series of chambers. This compressor is normally called a centrifugal compressor.
The frontal area of a centrifugal compressor as compared to axial flow compressor is larger or smaller?
the frontal area of a centrifugal compresor is more as compared to axial flow compressor for a given air flow. And for this reason axial compressors are being used in aircraft engines.
What is difference betweenrotar of centrifugal pump and compressor?
pump is used to handle liquid and compressor is used to handle gases. other difference include blade shape etc..
What is diaphragm used for a centrifugal compressor?
diaphrams are static ones containing guide blades...steam from suction end enters the suction diaphragm and get guided to impeller of centrifugal compressor..ntermediate diaphrams contains diffusers which changes pressure energy..these daphragms forms a part of inner casing.
Why flywheel is used in reciprocating compressor not in centrifugal compressor?
Flywheel prevents fluctuation in the speed of the motor as a result of load fluctuation. It stores the energy and dissipates it to the compressor for prolonged period. So the load fluctuation which is high during compression stage and low during other stages during a cycle in reciprocating compressor gets nullified. On the other hand, centrifugal compressor continiously compresses the gas and does not have load fluctuations, hence flywheel is not required.
What is the function of Bull gear in centrifugal compressor?
The bull gear in a centrifugal compressor is responsible for driving the impeller. It transfers rotational energy from the driver (such as an electric motor or a gas turbine) to the impeller, which then compresses the gas or air. The size and design of the bull gear impact the efficiency and performance of the compressor.
What can upset the balance between gravity and pressure in a nebular?
You used the term nebular. I take it you mean a galaxy. There would not be a balance between gravity and pressure. There would be a balance between gravity and centrifugal force.
What is the balance piston used for a centrifugal compressor?
Due to the pressure rise developed through the impeller, a pressure difference exists across the hubs and covers such that the impellers have a net thrust in the direction of the compressor inlet. The balance piston counteracts that by being located behind the last impeller. This is accomplished by subjecting the outboard side of the balance piston to a low pressure from the inlet side of the compressor thereby creating a pressure differential opposite to the direction of the impellers. This pressure is acheived by connecting the area behind the piston to the inlet using a line. The impeller thrust not balanced by the balace piston is absorbed by the thrust bearings. I hope this helps
Centrifugal force where it is been used?
Centrifugal force is used in a roller coaster.
