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. WebOne useful relation for understanding incompressible steady flows is Bernoulli’s equation. This equation relates the energy (kinetic and potential) per unit mass of a fluid to its …
