Water pressure vs temperature - Physics Stack Exchange

Webb18 juni 2006 · There is a pressure head, based on the elevation of the water. There is pressure based on the energy within the water, if the water is confined in a pipe, and there is the differential pressure applied to make the water flow in opposition to friction forces. Bernoulli's equation would be appropriate.
