  "term": "Pitot tube",
  "field": "Meteorology and atmospheric science",
  "definition": "In hydrologic terms, a device for measuring the velocity of flowing water using the velocity head of the stream as an index of velocity. It consists\nessentially of an orifice held to a point upstream in the water, connected with a tube in which the rise of water due to velocity head\nmay be observed and measured. It also may be constructed with an upstream and downstream orifice, with two water columns, in\nwhich case the difference in height of water column in the tubes is the index of velocity.",
