INTRODUCTION TO FLUID MECHANICS 6 TH EDITION JANNA UPDATED ACTUAL EXAM
QUESTIONS CORRECT ANSWERS GRADED A PLUS
⩥ 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.
⩥ How is fluid mechanics relevant to civil engineering? Answer: It is
fundamental in managing water flow, designing piping systems, and
flood control.
⩥ What role does fluid mechanics play in aerospace engineering?
Answer: It is central to aerodynamics, affecting aircraft design to reduce
drag and improve efficiency.
