Flow rate equation cross sectional area
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. WebK.E. = (mass flow rate) ⋅ (KE term from Bernoulli equation) K.E. = (ˉV ⋅ A ⋅ ρ) ⋅ ( ˉV2 2) Use the temperature, pressure, and composition of Earth air to calculate density ρ. Calculate A as cross sectional flow area of the pipe. ˉV is average velocity. Verbose exploration:
