FLUID MECHANICS UPDATED ACTUAL
QUESTIONS AND CORRECT ANSWERS
COMPLETE STUDY GUIDE FULL SOLUTION
●● What are the two main subfields of mechanics?
Answer: Statics (bodies at rest) and dynamics (bodies in motion).
●● What is fluid statics?
Answer: The branch of fluid mechanics that deals with fluids at rest and
the forces and pressure exerted by them.
●● What is fluid dynamics?
Answer: The area of fluid mechanics that focuses on the behavior of
moving fluids and the forces acting on them.
●● What is fluid kinematics?
Answer: The study of the motion of fluids without considering the forces
responsible for that motion.
●● What does Pascal's Law explain?
Answer: It explains how pressure is transmitted in a fluid at rest,
fundamental to fluid statics.
, ●● What is buoyancy?
Answer: The upward force exerted by a fluid that opposes the weight of
an object immersed in it.
●● What is density in the context of fluids?
Answer: The mass per unit volume of a fluid, influencing buoyancy and
pressure.
●● What is viscosity?
Answer: A measure of a fluid's resistance to flow, affecting how easily it
moves.
●● What is pressure in fluid mechanics?
Answer: The force per unit area exerted by a fluid, which varies with
depth in a static fluid.
●● What is flow rate?
Answer: The volume of fluid passing through a given area per unit of
time.
●● How is fluid mechanics applied in mechanical engineering?
Answer: It is used in designing pumps, turbines, HVAC systems, and
vehicles.
