It is desired to determine the surface tension of a particular fluid using a capillary-rise experiment. Kienth used a 0.5 mm glass tube and found that the height of the liquid measured 30 mm with a contact angle of 30°. Kienth then performed viscosity measurements using an Ostwald viscometer. He found that the fluid takes 1.5 times slower to flow through the viscometer relative to water with a density of 1000 kg/m? and a viscosity of 1.0 cP. It is previously known that the viscosity of the fluid is 1.35 cP. What is the surface tension of the liquid?

Question
It is desired to determine the surface tension of a particular fluid using a capillary-rise
experiment. Kienth used a 0.5 mm glass tube and found that the height of the liquid
measured 30 mm with a contact angle of 30°. Kienth then performed viscosity measurements using an Ostwald viscometer. He found that the fluid takes 1.5 times slower
to flow through the viscometer relative to water with a density of 1000 kg/m? and a
viscosity of 1.0 cP. It is previously known that the viscosity of the fluid is 1.35 cP. What
is the surface tension of the liquid?
