The continuity equation (article) | Fluids | Khan Academy Learn how to represent the volume flow rate of a fluid Explore how the incompressibility of liquids leads to the continuity equation The volume flow rate (Q) of a fluid is defined to be the volume of fluid that is passing through a given cross-sectional area per unit time
Volume flow rate and equation of continuity - Khan Academy Use an example of a pipe with different sized openings on either end to observe and quantify laminar flow of liquids Learn about the concept of flux, and how it is used to calculate the power of a system with moving fluid
Finding flow rate from Bernoullis equation - Khan Academy Let's use Bernoulli's equation to figure out what the flow through this pipe is Let's just write it down: P1 plus rho gh1 plus 1 2 rho v1 squared is equal to P2 plus rho gh2 plus 1 2 rho v2 squared
Putting it all together: Pressure, flow, and resistance But what we can figure out is that Q, the flow, will equal the stroke volume, and I'll tell you what this is just after I write it The stroke volume times the heart rate
Venturi effect and Pitot tubes (video) | Khan Academy This video breaks down Bernoulli's equation, revealing the surprising principle that faster fluid equals lower pressure It also introduces the Pitot tube, a practical tool for measuring fluid velocity
Fluid mechanics: Flow and Poiseuilles law in operation The relationship between flow, pressure, and resistance can be expressed similarly to Ohm’s law, where flow rate (F ) is directly proportional to the pressure difference (P 1 P 2 ) and inversely proportional to resistance (R ), as shown in Equation 1
Czym jest strumień objętości (artykuł) | Khan Academy So, we get a new formula for the volume flow rate Q = A v that is often more useful than the original definition of volume flow rate because the area A is easy to determine
