Funnels. |
a a′ are elevations and sections of a funnel, which has a discharge around the spout for the air displaced by the liquid.
b is a graduated funnel, which indicates the quantity of the contents.
See measuring-funnel.
c is a pierced filter of porcelain or glass, used in a laboratory, with a cone of bibulous paper inside.
d is a filter of similar use, but with heavy ridges, to keep the paper from adhering to the sides.
e is a combined measure, faucet, and funnel.
The filter-funnel should have sides which subtend an angle of 60°, for the reason that a sheet of bibulous paper, folded quarterly and one flap opened, forms a cone the vertical section of which is a triangle with sides forming that angle.
