Question
(a) Derive and explain the significance of :
(i) Froude's number
(ii) Mach number
(iii) Reynolds number.
(b) A pipe of diameter $1.8\text{ m}$ is required to transport an oil of sp. gr. $0.8$ and viscosity $0.04\text{ Poise}$ at a rate of $4\text{ m}^3\text{/s}$. Tests were conducted on a $20\text{ cm}$ dia. pipe using water at $20^\circ\text{C}$. Find the velocity and rate of flow in the model. Take viscosity of water at $20^\circ\text{C}$ as $0.01\text{ Poise}$.
