On the Loss of Head Resulting from the Passage of Water Through a 24-inch Stop Valve
Some time ago the writer had occasion to investigate closely the actual loss of head due to friction in a certain large water pipe under high pressure; and for the purpose of directly measuring this loss in a moderate length of pipe, he devised the simple apparatus shown on Plate XXXVII, where by the difference in the hydraulic pressures existing at any two points in a line of water pipe is at once exhibited by the difference in height of two communicating columns of mercury. The apparatus is, therefore, merely a pressure-difference gauge, which has the merit of being both sensitive and accurate, and which may also be applied in other similar investigations, such as the determination of the loss of head due to the passage of a certain quantity of water through a partially opened stop valve.
