Flow Rate and Its Relation to Velocity Physics
WebThe formula for calculating mass flow rate ṁ= ρVA. \dot {m}= 650× 30 × 0.25m = 8400 kg/s. The mass flow rate m for the above-given data is 4875 kg/s. Problem 2 :The mass flow rate of a fluid flowing through a circular pipe is 3600 kg/s, the velocity of the flow is 25 m/s and cross sectional area of the pipe is 10 cm 2. WebJun 13, 2024 · Using the depth and width measurements for calculating the area and the velocity measurements, the discharge is computed by the ADCP using discharge = area x velocity, similar to the conventional current-meter method. Acoustic velocity meters have also been developed for making wading measurements (picture to the left). WebFlow rate and velocity are related by Q = A¯v Q = A v ¯ where A A is the cross-sectional area of the flow and ¯v v ¯ is its average velocity. For incompressible fluids, flow rate at various points is constant. That is, Q1 = Q2 A1¯v1 = A2¯v2 n1A1¯v1 = n2A2¯v2. pop and cool hairstyles animal crossing
