How do I find viscosity of oil in a viscometer?
In a falling ball viscometer a steel ball with a dia. of 1.6mm is allowed to fall freely in a heavy fuel oil having a specific gravity of 0.94. Steel weighs 77kN/m^3. If the ball is observed to fall 250mm in 10.4s calculate the viscosity of the oil?
Can some one show me how to do it. I am close but I am missing something somewhere?
I really just would like to know how to find (gamma) specific gravity of the fluid using the information provided, but full explanation would also work well!
