Question

The pressure measured in the tire of your car is called absolute pressure. True or false? Pascals Law says that pressure exerted anywhere in a confined incompressible fluid is transmitted equally in all directions throughout the fluid. True or false? Piezometric pressure is defined as p/gamma + z; piezometric head is defined as p + gamma z True or false? What's the difference between Newtonian and non-Newtonian fluids? Give an example of each. Boiling of water or cavitation occurs at a lower temperature at a higher elevation than at a lower elevation. True or False? The hydrostatic force acting on a planar surface submerged horizontally in a liquid lies generally below the centroid of the submerged surface. True or False? The viscosity of liquids increases with a decrease of temperature while the viscosity of gases decreases with the increase of temperature True or false? The shear stress at the wall with a fluid moving over it is greater for laminar flow than for turbu

Explanation / Answer

1.TRUE

2.TRUE

3.FALSE

4. NEWTONIAN FLUID : A REAL FLUID IN WHICH THE SHEAR STRESS IS DIRECTLY PROPORTIONAL TO RATE OF SHEAR STRAIN IS KNOWN AS NEWTONIAN FLUID.

EG : WATER AND AIR

NON-NEWTONIAN FLUID : A REAL FLUID IN WHICH SHEAR STRESS IS NOT PROPORTIONAL TO SHEAR STRAIN IS KNOWN AS NON NEWTONIAN FLUID.

EG : CUSTARD ,KETCUP,SALT SOLUTIONS ETC;
