Determining the Viscosity of Liquids Using an Extended Falling Ball Method
Peer reviewed Peer reviewed
Direct linkDirect link
Houari, Ahmed – Physics Education, 2011
In this article, I will extend the falling ball method to measure the viscosity of liquids regardless of the degree of their viscosity. For this, I will show that one can obtain a measurement of the terminal velocity of a falling spherical ball in a viscous liquid by solving numerically the equation of motion which describes the dynamics of the…
