In a pipe flow, if radius of pipe is 5 cm & viscosity is 3 poise. Given the maximum velocity of flow of water under laminar condition is 10m/sec then Reynold’s number of flow is
Question 2
The dimension of kinematic viscosity (v) is
Question 3
The pressure difference between the inside and outside of a liquid droplet of diameter d due to surface tension (σ) is given by the relation
Question 4
A stream function is given by ψ = 4x - 3y The resultant velocity at any point is
Question 5
A steady, incompressible, two-dimensional velocity field is given by V = (u, v) (0.5 + 0.8x)i +(1.5 - 0.8y) j The number of stagnation points there in the flow field is
