Question:

A capillary type viscometer similar to that shown in Fig. 2.7 is being used to measure the viscosity of an oil having a specific gravity of 0.90. The following data apply:

Tube inside diameter = 0.100 in = D
Length between manometer taps = 12.0 in = L
Manometer fluid = mercury
Manometer deflection = 7.00 in = h
Velocity of flow = 4.82 ft/s = v

Determine the dynamic viscosity of the oil in lbˆ™s² /ft.
