How to perform quantitative calculations of the velocities before and after a fluid pipeline?
Thread Content
I’d like to ask the experts, as mentioned in the title. The Bernoulli equation states that P + (1/2)ρV² + ρgh = C (static pressure + dynamic pressure + gravitational potential energy = total pressure). If the pipe diameter suddenly decreases, with the flow rate remaining constant, the pressure in the pipe increases and the flow velocity also increases. So, how can the change in flow velocity be calculated quantitatively? ? ? All calculations can assume a constant flow rate.
Flow rate divided by cross-sectional area equals flow velocity
