At sea level under normal conditions the equivalent value of the atmospheric pressure is 1.03 kg/cm^2 10.3 m of water 76 cm of mercury all of the above2. If, for a fluid in motion, pressure at a point is same in all the directions , then fluid is a real fluid a Newtonian fluid an ideal fluid a non-Newtonian fluid3. 4. The centre of pressure of a liquid on a plane surface immersed vertically in a static body of liquid, always lies below the centroid of the surface area, because In liquids the pressure activity is same in all the directions There is no shear stress in liquids at rest The liquid pressure is constant over depth The liquid pressure increases linearly with depth5. For a fluid at rest, The shear stress is zero only for ideal fluids The shear stress is maximum on a plane inclined at 45 degree to horizontal The shear stress is zero also in real fluids The shear stress is zero only on horizontal planes6. A vertical triangular plane area submerged in water ,with one side in the free surface, vertex downward and altitude 'h' has the pressure centre below the free surface by h/4 h/3 2h/3 h/27. In a barometer, mercury is preferred over water because It is a better conductor of heat Its surface is easier to read It has a higher density and lower vapour pressure It has a higher vapour pressure and bulk modulus8. Barometer is used to measure Absolute pressure Gauge pressure Local atmospheric pressure All of the above9. When pressure is measured either above or below the atmospheric pressure, it is known as Gauge pressure Absolute pressure Atmospheric pressure Vacuum pressure10. If the pressure of a fluid is below the atmospheric pressure , its designated as Vacuum pressure Suction pressure Negative gauge pressure All of the aboveBe sure to click Submit Quiz to see your results!Please enter your mail id to get the correct answers on your mail.
