List of top Fluid Mechanics and Thermal Sciences Questions on Viscous flow of incompressible fluids

The velocity field of a two-dimensional, incompressible flow is given by
\(\overrightarrow{V} = 2 sinh\ x\ \vec{i} + v(x, y)\vec{j}\)
where \(\vec{i}\ \text{and}\ \vec{j}\) denote the unit vectors in x and y directions, respectively. If v(x, 0) = cosh x, then v(0, -1) is

Given below are two statements:
Statement I: Viscosity of liquids decreases with increase in temperature.
Statement II: Viscosity of liquids is appreciably affected by change in pressure.
In the light of the above statements, choose the correct answer from the options given below:

A linear spring mass-dashpot system with a mass of 2 kg is set in motion with viscous damping. If the natural frequency is 15 Hz, and the amplitude of two successive cycles measured are 7.75 mm and 7.20 mm, the coefficient of viscous damping in (N.s/m) is
