In a falling-ball viscometer, a steel ball 1.6mm in diameter 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, find the viscosity of the oil.© BrainMass Inc. brainmass.com October 9, 2019, 10:37 pm ad1c9bdddf
d = 1.6 mm = 0.0016 m
v = 250 mm / 10.4 s = 250 * 10^-3 m / 10.4 s = 0.024 m/s
Mass density of ...
