This experiment measures the viscosity of different liquid samples by timing how long it takes a steel ball to fall through each liquid. The terminal velocity of the falling ball is used to calculate the absolute viscosity of each sample based on Stokes' law.

This lab experiment measures the viscosity of different fluid samples using the ball drop method. A ball is dropped through a sample liquid and the time it takes to fall a set distance is measured, from which the terminal velocity is calculated.

Fd decreases the velocity. After some time the ball will move with a steady velocity, c. lled the terminal velocity. cylinder of inner radius R. To take into account the effect of the finite depth and radius of the liquid column two corrections, known as Ladenburg corrections, are introduced as multipliers of the.

This lab experiment uses the ball drop method to measure the viscosity of different liquid samples. A ball is dropped through a measured distance of each liquid sample and the time taken is recorded. This time and distance is used to calculate the terminal velocity of the ball.

This lab is designed to measure fluid viscosity using a small ball drop device. The device allows for viscosity measurement of fluid filled into a thin capillary. The technique is particularly useful in characterizing biological fluids such as solutions of proteins, DNA, and polymers frequently used in biomaterial applications. Introduction:

Figure 1 is a schematic of a falling ball viscometer. A sphere of known density and diameter is dropped into a large reservoir of the unknown fluid. At steady state, the viscous drag and buoyant force of the sphere is balanced by the gravitational force.
