FLUID MECHANICS
1. THE UNIT OF KINEMATICS VISCOSITY IS :- cm^2 / sec
2. AN IDEAL FLUID IS :- friction less and incompressible
3. PASCAL-SECOND IS THE UNIT OF :- dynamic viscosity
4. SURFACE TENSION OF WATER:- increase with decrease in temperature
5. NEWTON'S LAW OF VISCOSITY RELATES:- Shear stress and rate of an gular deformation
6. ONE KILO-PASCAL IS EQUIVALENT TO:- 0. 01 bar
7. CENTER OF BUOYANCY ALWAYS :- coincides with centroid of the volume of FLUID displaced
8. THE PITOT TUBE IS USED TO MEASURE :- stagnation pressure
9. HOT WIRE ANEMOMETER IS USED TO MEASURE :- velocity of gas
10. THE PRESSURE AT SUMMIT OF A SYPHON IS:- less than atmospheric
