A conical measure is a type of laboratory glassware which consists of a conical cup with a notch on the top to allow for the easy pouring of liquids, and graduated markings on the side to allow easy and accurate measurement of volumes of liquid. They may be made of plastic, glass, or borosilicate glass. The use of the conical measure usually ...
The tun (Old English: tunne, Latin: tunellus, Middle Latin: tunna) is an English unit of liquid volume (not weight), used for measuring wine, oil or honey.It is typically a large vat or vessel, most often holding 252 wine gallons, but occasionally other sizes (e.g. 256, 240 and 208 gallons) were also used.
In general, a conical surface consists of two congruent unbounded halves joined by the apex. Each half is called a nappe, and is the union of all the rays that start at the apex and pass through a point of some fixed space curve. [2] Sometimes the term "conical surface" is used to mean just one nappe. [3]
A hogshead of brandy was approximately equal to 56–61 gallons (0.255–0.277 m 3). [ citation needed ] Eventually, a hogshead of wine came to be 52.5 imperial gallons (238.669725 L ) (63 US gallons), while a hogshead of beer or ale came to be 54 gallons (249.5421 L with the pre-1824 beer and ale gallon, or 245.48886 L with the imperial gallon).
Ships in that size range can carry between 2.5 million and 3.5 million gallons of fuel. The amount of fuel actually be used on a sailing depends primarily on the ship's speed.
The Builder's Old Measurement formula remained in effect until the advent of steam propulsion. Steamships required a different method of estimating tonnage, because the ratio of length to beam was larger and a significant volume of internal space was used for boilers and machinery. In 1849, the Moorsom System was created in the United Kingdom ...
Typically a large vat or vessel, most often holding 252 wine gallons, but occasionally other sizes (e.g. 256, 240 and 208 gallons) were also used. [2] The modern tun is about 954 litres. The word tun is etymologically related to the word ton for the unit of mass, the mass of a tun of wine being approximately one long ton , which is 2 240 pounds ...
Both the conical plate centrifuge and chamber bowl centrifuge can be used for liquid/liquid and solid/liquid separation. However, the advantage of conical plate centrifuge over chamber bowl centrifuge is that solid discharge is possible in conical plate. The chamber bowl has a high capacity for solids but there is no solid discharge.
