Question

In a falling-ball viscometer, a steel ball with a diameter of 0.063 in is allowed to fall freely in a heavy fuel oil having a specific gravity of 0.94. Steel weighs 0.283 lb/in³. If the ball is observed to fall 10.0 in in 10.4 s, calculate the dynamic viscosity of the oil in lb·s²/ft.

Step 1

The volume \( V \) of a sphere is given by the formula \( V = \frac{4}{3} \pi r^3 \), where \( r \) is the radius of the sphere. First, convert the diameter of the steel ball from inches to feet (since 1 inch = 1/12 feet). The diameter in feet is \( 0.063 \) in Show more…
