Which of the following velocity fields represents a possible fluid flow? u=x, v=y u=x^2, v=y^2 u=xy, v=x^2. y^2 u=x, v=-y2. A perfect fluid (ideal fluid) is A real fluid The one which obeys perfect gas laws Compressive and gaseous Incompressible and frictionless3. Newton's law of viscosity relates Intensity of pressure and rate of angular deformation Shear stress and rate of angular deformation Shear stress, viscosity and temperature Viscosity and rate of angular deformation4. The unit of Dynamic viscosity is m^2/s N.s/m^2 Pa.s/m^2 Kg.s^2/m^25. The increase in metacentric height Increases stability Decreases stability Increases comfort for passengers All of these6. Which of the following pressure units represents the least pressure? Millibar mm of mercury N/mm^2 kgf/cm^27. Pascal-second is the unit of Pressure Kinematic viscosty Dynamic viscosity Surface tension8. Viscosity is a property that manifests A fluid-solid boundaries only Between two adjacent -fluid layers in relative motion in uniform incompressible flows Only in turbulent flows9. If the dynamic viscosity of a fluid is 0.5 poise and specific gravity is 0.5 , then the kinematic viscosity of that fluid is 0.25 0.50 1.0 2.010. With increase in temperature ,viscosity of a fluid Does not change Always increases Always decreases Increases , if the fluid is a gas and decreases , if its a liquidBe sure to click Submit Quiz to see your results!Please enter your mail id to get the correct answers on your mail.
