Then for a given amount of water flowing from reservoir to container the level ... WebApr 28, 2024 · R. R is the ideal gas constant. Although the ideal gas constant was created to refer to gasses and how they diffuse and behave, it also applies to liquids. In chemistry, both liquids and gases are considered “fluids” – particles that are able to diffuse freely, as opposed to solids, whose particles are held in place by strong bonds. T
WebConservation of energy tells you that the pressure in the reduced area will be lower because the velocity is increased (speeding a fluid up lowers it pressure, some what counter intuitive because we think of pressure in terms of force not potential energy) Flow rate (Q) = velocity * Area. Q1 = Q2 v1 * A1 = v2 * A2.
