In a falling ball viscometer, a steel ball 1.2 mm in diameter is allowed to fall freely in a heavy oil having s= 0.802. The Steel specific weight is 77 kN/m3. If the ball observed to fall 250 mm in 10.4 seconds, calculate the viscosity of the oil?
A 3 layered density tower includes 30 cm glycerin (D = 1260 kg/m3), 25 cm oil (D = 950 kg/m3), and 20 cm gasoline (D = 740 kg/m3). What is the absolute pressure against the bottom of a container?
Determine the force required to move a thin plate of 30 x 60 cm2 size through a liquid of viscosity ? = 0.05 kg/ms at a velocity of 0.40 m/sec. The liquid is filled between two long parallel plates as shown in the Figure.
