摘要:
One method of field flow measurement is discussed. The Pitot orifice tube is inserted through a corporation cock in the side of a main. A cap having an ordinary pressure gage tapped into it is placed on the hydrant nozzle, allowing discharge to take place through the other nozzles. A formula to determine hydrant discharge is also discussed along with the practical uses of hydrant flow tests.

摘要:
This article discusses the necessity of good plant design to promote a “good impression” to consumers and to prevent avoidable accidents. If an operator finds the need to add certain design features to an existing plant, recommendations should be made to city councils with sufficient background information to permit a favorable decision to be made.
