The unit of kinematic viscosity is a) gm/cm-sec2 b) dyne-sec/cm2 c) gm/cm2-sec d) cm2/sec Ans: d 4. If the dynamic viscosity of a fluid is 0.5 poise and specific gravity is 0.5, then the kinematic viscosity of that fluid in stokes is a) 0.25 b) 0.50 c) 1.0 d) none of the above Ans: c 5. The viscosity of a gas a) decreases with increase in temperature b) increases with increase in temperature c) is independent of temperature d) is independent of pressure for very high pressure intensities Ans: b 6. Newton,s law of viscosity relates a) intensity of pressure and rate of angular deformation b) shear stress and rate of angular deformation c) shear stress, viscosity and temperature d) viscosity and rate of angular deformation Ans: b 7. An open tank contains 1 m deep water with 50 cm depth of oil of specific gravity 0.8 above it.

The position of center of pressure on a plane surface immersed vertically in a static mass of fluid is a) at the centroid of the submerged area b) always above the centroid of the area c) always below the centroid of the area d) none of the above Ans: c 9. The total pressure on a plane surface inclined at an angle 9 with the horizontal is equal to a) PA b) pA sin 9 c) pA cos 9 d) pA tan 9 where p is pressure intensity at centroid of area and A is area of plane surface. Ans: a 10. A vertical rectangular plane surface is submerged in water such that its top and bottom surfaces are 1.5 m and 6.0 m res-pectively below the free surface. The position of center of pressure below the free surface will be at a distance of a) 3.75 m b) 4.0 m c) 4.2m d) 4.5m Ans: c 11. Centre of buoyancy always a) coincides with the centre of gravity b) coincides with the centroid of the volume of fluid displaced c) remains above the centre of gravity d) remains below the centre of gravity Ans: b 12.
