Question
(a) Differentiate between :
(i) Practical and Ideal fluids
(ii) Cohesion and Adhesion
(iii) Dynamic viscosity and Kinematic viscosity.
(b) A plate $1\text{ sq m}$ in area and weighing $150\text{ N}$ slides down an inclined plane of angle $\theta = \sin^{-1} 5/13$, with a velocity of $0.5\text{ m/s}$. If the thickness of the oil film over the plane is $1.5\text{ mm}$, calculate the dynamic viscosity of the oil.
(c) A wooden beam $0.1\text{ m} \times 0.15\text{ m} \times 3\text{ m}$ floats on water. When the beam carries a $30\text{ N}$ load at the right end, it gets tilted by $1.5^\circ$ so that the right end is exactly at the water surface, find the specific weight of wood.
