Study Notes
Fluid Mechanics
- At severe arterial stenosis, the pressure drop is too high, resulting in not enough blood flowing through.
- Mild stenosis: pressure drop is moderate.
- Severe stenosis: pressure drop is very high.
Bernoulli Equation
- The equation relates the pressure of a fluid to its velocity: v² + p/ρ = const.
- Applies to steady-state and laminar flow.
- States that the sum of the kinetic energy and potential energy of a fluid is constant.
Aerodynamic Lift
- The shape of an airfoil is designed such that the air velocity above is faster than the velocity below.
- This results in less pressure above than below the airfoil, creating a lift (force).
Reynolds Number (Re)
- Developed by Osborne Reynolds (1842-1912).
- Measures the nature of fluid flow (laminar or turbulent).
Venturi Effect
- High flow velocity corresponds to low pressure, and high pressure corresponds to low flow velocity.
- Experimentally demonstrated by Giovanni Battista Venturi (1746-1822).
Euler Equation
- A mathematical equation describing fluid flow in the absence of friction (laminar flow).
- Relates the velocity of a fluid to its pressure and density.
