FAQs
Question: What is the difference between laminar and turbulent flow? Answer: Laminar flow is smooth and orderly, while turbulent flow is chaotic and irregular, often characterized by eddies and vortices.
Question: How do I apply Bernoulli's equation correctly? Answer: Ensure that the flow is steady, incompressible, and frictionless, and apply the equation between two points along a streamline.
Ready to enhance your understanding of fluid flow? Dive into our practice MCQs and test your knowledge to excel in your exams. Every question you solve brings you one step closer to mastering this essential topic!
Q. In which condition is turbulent flow most likely to occur?
A.
High viscosity
B.
Low velocity
C.
High flow rate
D.
Small diameter
Solution
Turbulent flow is most likely to occur at high flow rates, where the inertial forces overcome the viscous forces.
Q. Which factor does NOT affect the viscosity of blood?
A.
Temperature
B.
Hematocrit level
C.
Blood vessel length
D.
Plasma protein concentration
Solution
Blood vessel length does not affect the viscosity of blood; viscosity is influenced by temperature, hematocrit level, and plasma protein concentration.
