Mechanical Properties of Fluids Quiz

Study Notes

Pressure-Volume Relationship

Boyle's law states that pressure and volume of a gas are inversely related at constant temperature.
When the volume of a gas decreases, its pressure increases, and vice versa.

Viscosity

The SI unit of viscosity is the Pascal-second (Pa·s).
Viscosity measures a fluid's resistance to deformation or flow.

Flow Rate Calculation

The flow rate of a fluid through a pipe is calculated using the formula:
- Flow Rate (Q) = Area (A) × Velocity (v).
Area is the cross-sectional area of the pipe, while velocity is the speed of the fluid.

Moment of Inertia

Moment of inertia quantifies an object's resistance to rotational motion.
It is dependent on the mass distribution relative to the axis of rotation and has units of kg·m².

Torque in Rotational Dynamics

Torque is a measure of the force that causes an object to rotate about an axis.
It is calculated as: Torque (τ) = Force (F) × Distance (d) × sin(θ), where θ is the angle between the force and the lever arm.

Angular Momentum

Angular momentum is the rotational equivalent of linear momentum.
It is calculated as: Angular Momentum (L) = Moment of Inertia (I) × Angular Velocity (ω).
It is conserved in an isolated system unless acted upon by an external torque.
