Question
C1 (a). A lubricating oil having the dynamic
viscosity of 0.052 poise and kinematic viscosity of
0.19 stokes. Calculate (i) the density of oil in kg/m³,
(ii) the weight density of oil in N/m³,(iii) the specific
gravity, and (iv) the specific volume in m3/kg. (4
Marks)
C1 (b). Calculate the capillary effect in mm in a
glass tube of 4.2 mm diameter, when immersed in
(1) water (2) mercury. The values of surface
tension in contact with air are 0.0771 N/m and 0.64
N/m respectively. The contact angle for water =0°
and mercury =130°. (3 Marks)
