Question:

A capillary tube 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 = 2.5 mm = D
Length between manometer taps = 300 mm = L
Manometer fluid = mercury
Manometer deflection = 177 mm = h
Velocity of flow = 1.58 m/s = v
Determine the viscosity of the oil.
