2. Enter a value between 3 and 4 (to two decimal places):
1. Select the properties of a Newtonian fluid:
1. Enter a value between 3 and 4 (to two decimal places):
1. For a Newtonian fluid
2. The SI unit of kinematic viscosity (v) is
3. An incompressible fluid (kinematic viscosity = 7.4 × 10−7, specific gravity, 0.88) is held between two parallel plates. If the top plate is moved with a velocity of 0.5 m/s while the bottom one is held stationary, the fluid attains a linear velocity profile in the gap of 0.5 mm between these plates; the shear stress in Pascal on the surface of bottom plate is
4. The relationship between Young's modulus (E), Bulk modulus (K) and Poisson's ratio (µ) is given by:
5. A two dimensional fluid element rotates like a rigid body. At a point within the element, the pressure is 1 unit. Radius of the Mohr’s circle, charactering the state of stress at the point, is
6. A flow field which has only convective acceleration is
7. A streamline and an equipotential line in a flow field
8. Streamlines, path lines and streak lines are virtually identical for
