By fluting the filter paper we can maximize the rate at which the solvent may flow through the filter paper. This will increase the surface area of the air flown into the flask along the sides to permit rapid pressure equalization.

Why is vacuum filtration faster than gravity filtration?
Vacuum filtration is used instead of gravity filtration in order to achieve a dryer product in less time. The faster process of vacuum filtration allows the slurry to remain cold and in cases such as with benzoic acid more crytals will remain formed at colder temperatures. Gravity filtration is most useful when the solid is to be discarded and the filtrate (the liquid that flows through the filter paper) kept. Vacuum filtration is often faster than gravity filtration and is most useful if the solid must be kept or if a filtration must be done rapidly. A vacuum from an aspirator or a vacuum pump is used to pull the liquid through a funnel containing a piece of filter paper, while the solid is left on the paper.
What is Grade eight science filtration?
I'm guessing you mean Filtration as in Mixtures-Homogeneous Mixtures and Heterogeneous Mixtures. Well Filtration is for emulsions or dirty water. You put the water/liquid in filter paper attached the the stand and after a while the pure water seeps through the filter paper and you get clean water.
When do we use filtration?
We use filtration when we want to separate a solid and a liquid. e.g. chalk and water The residue left behind at the filter paper will be chalk in this case, for it is a solid:)
What is fillteration?
*Filtration - Darling, learn how to spell before you put a basic question up. Filtration is used to separate solids (Such as sand or small rocks) from liquids. It is set up using a funnel, filter paper, a stand and a beaker to hold the filtrate. The liquid is poured into the funnel, the solid is trapped in the filter paper and the liquid passes through into the beaker - the liquid is then called 'filtrate'.
What is filter in science?
Filtration is a process of separating a mixture of solid suspended in liquid. A filter paper is used in the process , then the mixture is poured over the filter paper , the liquid passes , but the solid particles suspended in the liquid , are stopped by the filter paper as residue. Thus , They get separated.
How the fluted filter paper increased the rate of filtration?
Rate of filtration can be increased by using fluted filter paper.rate of filtration is related to surface area of the filter medium.In case of fluted filter paper surface area is increased ,as by folding the paper in such a way,the larger area of filter paper can be confined in the same funnel.so rate of filtration increases.
What is the advantage of using fluted filter paper?
Fltuted Filter paper is essentially when you fold a sheet of filter paper in a certain way as to maximise it's surface area. More surface area means more effective filtration http://www.chem.ubc.ca/courseware/235/danalabsess/flutedfilterpaper.html
Why is fluted filter paper used in filtration process?
There are two primary advantages to fluted filter paper. One is the increase in filter area. The second, and probably the more effective of the two, is the fluting creates gaps between the filter paper and the funnel in which it is resting. These gaps provide channels for the solvent to flow through after it passes through the filter paper, thus greatly increasing the speed of solvent flow through the paper. This effect is most noticeable with the finer filter papers.
Why is the corner torn off in a gravity filtration?
To create an air tight seal between the funnel and filter paper.
Why is fluted filter paper used instead of an ordinary filter paper cone?
Fluted paper is used for filtering because it offers a greater surface area. By fluting the paper, the surface area can be increased by quite a bit, depending upon the number of flutes and the depth of each flute.
Why are stemless funnels used instead of long stem funnels to filter hot solutions through fluted filter paper?
In hot gravity filtration situations, a stemless funnel is used to prevent premature recrystallization.

What is quantitative filter paper method in cfu?
filtration
What do you bcall the solid remains on the filter paper after filtration?
residue
When you carry out a filtration what is the residue and what is the filtrate?
Filtration is a process used for separating the components from a mixture of immiscible substances.However different kinds of mixtures require various separation techniques and filtration is one such process. When filtration is done using a suitable filter (like a filter paper)the solid matter left on the filter paper can be called the residue and the liquid countertpart is the filtrate
Why gooch crucible is preferred over filter paper?
crucibles are prefer over filter paper because filtration by crucibles are efficient as that of filtration by filter paper and Gooch crucible is preffered due to its suction force that make the process of filtration faster
Can you separate the cornstarch from water without using filter paper why?
The only way to separate cornstarch and water is my filtration so you would have to use filter paper or something similar.
