Language: English . Brand New Book ***** Print on Demand *****.Excerpt from The Venturi Meter: Patented by Clemens Herschel, Hydraulic Engineer and by Builders Iron Foundry, Made by Builders Iron Foundry, Founders and Machinists Loss of Head.due to the friction in passing through the meter. The exact differences for the various velocities of flow in cubic feet per second through the throat of the meter are shown by the column Friction head in feet in the tables at the end of this book. Another way of actually seeing how slight is the loss of head is by using ordinary pressure gauges in place of glass water tubes. The illustration shows two such gauges; one connected with the up-stream and the other with the down-stream end of a 36-inch meter with a flow of water 7 cubic feet per second through the throat. The variation between the two gauges is 17 of a foot, an amount too slight to be of any practical importance in Water Works systems. The reasons why the loss of head is so slight have long been known, but are not easily explained without technical terms. They were first noted by the Italian philosopher Venturi in 1796, and for him the meter is named. Numerous investigators have studied the subject, and it is well described on pages 466 and 467 of the 9th edition of the Encyclopedia Britannica, and in Article 71 of Professor Mansfield Merriam s treatise on Hydraulics, and in the paper which received the Rowland Prize when read by the inventor of the meter, Mr. Clemens Herschel, before the American Society of Civil Engineers, December 213t, 1877. Reprints of these articles we can furnish upon application. The construction of the meter may be modified according to different conditions under which it is used, so that, in every case, the loss of head may be reduced to any desired minimum.
