What is flooding point?
In a packed or tray column where you have vapor flowing up and liquid flowing down, there is an upper limit to how fast the liquid can drain downwards. The point at which liquid cannot flow down as fast as it is coming into the column is the "flooding point". The actual flooding point is partly dependent on how fast the liquid can flow down with no vapor flowing upwards and the rate at which vapor is trying to flow upwards. Cross sections of the column occupied by vapor are not available for liquid flow - effectively reducing the cross-section for downward flow of the liquid. You also get entrainment of liquid in the upward flowing vapor and drag on the liquid as it fights the direction of the vapor flow - the vapor wants to go up while the liquid wants to go down. This additional drag also slows down the flow of liquid trying to drain downward in the column. There is an analogous condition for two-phase liquid/liquid extraction columns.
What type of trays can be found in a distillation column besides bubble cap sieve and valve trays?
The gas-liquid contacting element for bubble cap tray is bubble cap, which has round and groove-shaped structure forms. The bubble cap is installed above the chimney, and will not leak in conditions of proper installation and gas-liquid load, so the bubble cap tray is featured by stable operation and great flexibility. For structural reasons, the liquid level on the tray is relatively high, and two-phase contact is of long time. Therefore, the pressure drop is high, entrainment is increased, and the fall in the liquid level on the tray is relatively great, etc www.rubbersealing.com
Do you use teflon tape with a union coupling?
You use it on the pipe that the union is connected to, but not on the threads of the union itself. The union seals where the two halves join and there is no liquid or gas in contact with the threaded part of the union.
What is the Definition for simple distillation?
The two most elementary forms of distillation are a continuous http://www.answers.com/topic/equilibrium-flash-vaporization and a simple http://www.answers.com/topic/batch-distillation. In a continuous equilibrium distillation, a continuously flowing liquid feed is heated or reduced in pressure (flashed) so as to cause partial vaporization. The vapor and liquid disengage while flowing through an open drum, and the products emerge as vapor and liquid streams. The vapor product can be condensed to form a liquid distillate. It is also possible to use a vapor feed, subjected to cooling and thereby http://www.answers.com/topic/partial-condensation, again followed by http://www.answers.com/topic/disengagement of the resultant vapor and liquid in an open drum. In a simple batch distillation, an entire batch of liquid is initially charged to a vessel and is then heated, typically by http://www.answers.com/topic/condensation of steam inside a metal http://www.answers.com/topic/coil within the vessel. Vapor is thereby continuously generated, and may be condensed to form a liquid distillate, which is collected. In the batch distillation, increments of vapor are formed in equilibrium with all liquid compositions ranging from the original to the final, whereas the continuous equilibrium distillation gives vapor in equilibrium with only the final liquid composition. Since the distillate consists primarily of the more volatile components and the feed liquid contains more of these substances than does the final liquid, the simple batch distillation gives a more http://www.answers.com/topic/enrichment distillate than does the continuous equilibrium distillation.
How many coil of aph in boiler?
two types of air pre heaters used in thermal power plants . One is a tubular type built into the boiler flue gas ducting, and the other is a regenerative air preheater.These may be arranged so the gas flows horizontally or vertically across the axis of rotation.
What is compound manometer?
Compound Manometer is an 'U' Tube manometer having 'T' joints at appropriate equal elevation in the columns of U tube manometer where the impulse lines are to be connected to measure Differential Pressure. T joint allows the use Two liquids simultaneously in the manometer. i.e. the liquid who's differential pressure is to be measured being lighter it will gauge at the top and a heavier liquid which does not dissolve with the lighter fluid will gauge at the bottom. Elevation difference in lighter liquid as well as heavier liquids gives their respective differential pressure. Both the differential pressure will be equal in terms of Pressure Units. Since two liquids are used simultaneously this type of U tube manometer is called Compound Manometer.
What are the classes of manometer?
There are two classes of manometer. The two classes are accuracy class and types.
What is an electrical manometer?
Electrical manometer is an electronic manometer use to record pressures between two points. It is commonly used in recording pressure in bridges.
What are manometer?
what is a manometer? and what is application of manometer in industrial? A Manometer is a device which can be used to measure pressure of fluids(i.e liquids and Gases). PRINCIPLE: Manometers are those pressure measuring devices which are based on the principle of balancing the column of liquid(whose pressure is to be found) by the same or another column of liquid. They are of two types 1. simple manometers 2.Differential manometers simple manometers are those which measure pressure at a point in a fluid containing in the pipe or a vessel. On the other hand Differential manometers measure the difference of pressure between any two points in a fluid contained in a pipe or vessel. Industrial applications: Pressure guages are used for a variety of industrial and application specific pressure monitering applications. visual monitering of air and gas pressure for compressors,Vaccum equipment and speciality tank applications such as medical gas cylinders, fire extinguishers,
Investigate the application of hydrostatics to manometer measurement of fluid flow?
According to Bernoulli's principle, the sum of static, velocity and kinetic heads at two points in a fluid flow should be equal, assuming steady state. A manometer measures static head through the height of fluid at two points. Hence, it would be apt to say that manometer is an application of hydrostatic measurement.
What are the uses of the manometer?
air, fluids and very low pressures equal & unequal leg u tube manometer, cistern manometer, u tube manometer.
Why the water levels in the various Manometer tubes are different?
The reason the water levels in the various manometer tubes are different is because of the difference in pressure. A manometer is used to measure the pressure between two different systems.
Why liquids have two coefficients of expensions?
liquid has two coefficient of expensionbecause during expension by heating the expension of container as well as expension of liquid takes place. that is why liquid have two coefficient of expension
