Lesson 504 of 1524
Fluid Dynamics and Its Biological and Medical Applications
Flow rate and velocity are related by Q = A v ¯ where A is the cross-sectional area of the flow and v ¯ is its average velocity
Practice this chapterFlow rate and velocity are related by Q = A v ¯ where A is the cross-sectional area of the flow and v ¯ is its average velocity Flow rate Q is defined to be the volume V flowing past a point in time t , or Q = V t where V is volume and t is time
Another common unit is the liter (L), which is 10 - 3 m 3 For incompressible fluids, flow rate at various points is constant.
fluid dynamics — the physics of fluids in motion. flow rate — abbreviated Q , it is the volume V that flows past a particular point during a time t , or Q = V/t. v ¯ where A — the cross-sectional area of the flow and v ¯ is its average velocity. Bernoulli’s equation — the equation resulting from applying conservation of energy to an incompressible frictionless fluid: P + 1/2 pv 2 + pgh = constant , through the fluid.
Worked example
What does “fluid dynamics” mean in Fluid Dynamics and Its Biological and Medical Applications?
- 1Use the wording this chapter gives for fluid dynamics.
- 2The book says: the physics of fluids in motion.
- 3Do not use the meaning of flow rate. That term means abbreviated Q , it is the volume V that flows past a particular point during a time t , or Q = V/t.
Result: the physics of fluids in motion
Why. That is the meaning this chapter gives for fluid dynamics.
Do not swap fluid dynamics and flow rate. fluid dynamics means the physics of fluids in motion. flow rate means abbreviated Q , it is the volume V that flows past a particular point during a time t , or Q = V/t.
