What property of fluids is defined as the friction within the fluid and between the fluid and its surroundings?
Viscosity
Which substance would likely have high viscosity?
Syrup
In non-viscous flow, what is true about the movement of different layers of the fluid?
All layers move with the same velocity
What is the critical velocity that marks the transition from streamline flow to turbulent flow?
$V_c = Rvn$
Which fluid, at about 2K, is considered almost non-viscous?
Liquid helium
What distinguishes the flow of a fluid as either streamline or turbulent?
Viscosity of the fluid
What is the relationship between the velocity of an object moving through a viscous fluid and the terminal velocity of that object?
The velocity is always less than or equal to the terminal velocity.
In the equation of continuity in fluid dynamics, what does 'Av' represent?
Volume rate of flow of the fluid
What does 'ρdV/dt = dm/dt' represent in fluid dynamics?
Mass flux
Why does a particle have to move faster in a narrower section of fluid flow according to the text?
Due to conservation of mass
What is the formula for the volume rate of flow of a fluid, as given in the text?
$48Av$
In a steady flow of an incompressible fluid, what remains constant at a given point?
Velocity
What is the main reason for limiting the study to the motion of an ideal fluid in the text?
To simplify the study due to the complexity of real fluid motion
What is the difference between a flow line and a streamline in a moving fluid?
Flow line shows path of an individual particle, while streamline shows tangent at any point
What defines a steady flow according to the text?
Smooth movement of layers over each other
Which type of flow is characterized by a continuously changing flow pattern?
Turbulent flow
In a steady flow, what happens to fluids in adjacent flow tubes?
They mix together
What is the function of a flow tube in fluid dynamics?
To bind an imaginary bundle of flow lines
In a conical pendulum system, what happens if the string becomes horizontal?
Both a and b are correct.
Why can't the string in a conical pendulum system ever become horizontal?
Both a and b are accurate reasons.
What forces act on the bob in a conical pendulum system in a given position?
mg directed vertically downwards and T0 along the string towards support A.
How does a conical pendulum bob move?
In a horizontal circular motion.
What would happen if the angle 'i' in a horizontal string setup is 90°?
Both b and c are consequences of angle 'i' being 90°.
Why is it impossible for a conical pendulum's frequency to become infinite?
Because it would imply infinite kinetic energy of the bob.
