  "id": "MLC-T-OAG-003451",
  "term": "Slip",
  "field": "Oil and gas",
  "definition": "The difference in velocity between two or more fluid phases flowing together in a pipe, where the lighter, less dense phase moves faster than the heavier, denser phase. In an oil-water-gas flow, gas moves fastest and water moves slowest due to density and viscosity differences. This velocity difference, known as slip velocity, is a key parameter in multiphase flow calculations and is expressed in units of length per time, such as feet per minute.",
