Flashcards
Boyle's Law
Boyle's Law
The relationship between pressure and volume of a fluid, stating that pressure is inversely proportional to volume. This means if you increase the pressure, the volume decreases, and vice versa.
Viscosity
Viscosity
The resistance of a fluid to flow. It describes how 'thick' or 'thin' a fluid is.
Flow rate
Flow rate
The amount of fluid that passes through a pipe per unit time. It's determined by the pressure, pipe size, fluid viscosity, and pipe length.

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.
