Flow rate formula physics
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. WebJun 21, 2024 · Using the formula we have, Q = Av = 20 (10) = 200 m 3 /s. Problem 2: Calculate the flow rate of liquid moving in a pipe of cross-section 15 m 2 at a velocity of 12 m/s. Solution: We have, A = 15. v = 12. Using the formula we have, Q = Av = 15 (12) = 180 m 3 /s. Problem 3: Calculate the flow rate of a liquid moving in a pipe of radius 2 m at a ...
