### measurement of viscosity in a vertical falling ball

Oct 27, 2008 The falling ball viscometer is well-suited for measuring the viscosity of a fluid, and the method has been stated in international standards. 4,5 In the international standards, the method differs from the principle described in Refs. 13. The standards describe an inclined-tube method in which the tube for the falling ball was inclined at 10

To verify this, the experiment was repeated with a steel ball bearing which gave the value of viscosity as 10.0 Poise. In the case of the steel ball, the time taken for travelling the distance of 0.4m is 0.377s. The value of viscosity obtained (6.8 Poise) employing smaller diameter (38mm) acrylic tube

Stokes' law describes sedimentation of particles in liquids and can be used to measure viscosity. Particles in liquids achieve terminal velocity quickly. One can measure the time it takes for a particle to fall a certain distance and then use Stokes' law to calculate the viscosity of the liquid. Suppose a steel ball bearing (density $7.8 \times 10^{3}\textrm{ kg/m}^3$ , diameter 3.0 mm ) is dropped in a container

### a steel ball is used to measure the viscosity of motor oil

Jun 26, 2020 A steel ball is used to measure the viscosity of motor oil. The container used in this experiment has a bottom area of 20 cm^2. The steel ball is 3 mm in diameter. After the ball is dropped to the container it takes about 12 seconds to reach the bottom of the container whose height is 60 cm. Calculate the viscosity of the motor oil

### measuring viscosity - activity - teachengineering

Jul 20, 2021 Students calculate the viscosity of various household fluids by measuring the amount of time it takes marble or steel balls to fall given distances through the liquids. They experience what viscosity means, and also practice using algebra and unit conversions. This engineering curriculum aligns to Next Generation Science Standards

Double-gap systems [14] are a special form of concentric cylinders, specially devised for measuring low-viscosity liquids. The cup is not a hollow cylinder, nor is the measuring bob a solid body. A second cylinder is placed in the center of the cup and the bob is shaped like an inverse cup that turns in the ring-shaped gap between the cups
