Viscosity
- Viscosity describes a fluid's resistance to flow.
- Viscosity is measured using Stoke's Law
Factors Affecting Viscosity
-
Temperature: Viscosity decreases as the temperature of a liquid increases.
- This is because the kinetic energy of the molecules increases, weakening intermolecular forces of attraction.
- For gases, the relationship is reversed: viscosity increases with temperature.
-
Molecular weight: Viscosity increases as the molecular weight of a liquid increases.
- Larger molecules lead to more intermolecular interactions, increasing resistance to flow.
Measuring Viscosity With Stoke's Law
-
Procedure:
- Set up the experiment with a glass tube filled with the liquid (glycerin).
- Select several steel balls with different diameters, measured using a micrometer.
- Choose two calibration marks, ensuring the balls fall with terminal velocity between them.
- Drop a ball centrally down the tube, starting the stopwatch at the first mark and stopping it at the second.
- Calculate the velocity of the ball by dividing the distance between the marks by the measured time.
- Repeat this process for all the balls.
- Use the equation derived from Stoke's Law to calculate the coefficient of viscosity.
Hemorheology
- Blood viscosity is primarily determined by two factors:
- Plasma Viscosity: The viscosity of the liquid portion of blood.
- Hematocrit: The percentage of red blood cells in the blood.
