A twodimensional incompressible frictionless flow field is given by $\overrightarrow{u} = x \hat{i} – y \hat{j}$. If $\rho$ is the density of the fluid, the expression for pressure gradient vector at any point in the flow field is given as $\rho(x \hat{i}+y \hat{j})$ $ – \rho(x \hat{i}+y \hat{j})$ $\rho(x \hat{i} – y \hat{j})$ $ – \rho(x^2 \hat{i}+y^2 \hat{j})$

The transition Reynolds number for flow over a flat plate is $5^*10^5$. What is the distance from the leading edge at which transition will occur for flow of water with a uniform velocity of $1 \: m/s$? (For water, the kinematic viscosity $v=0.86^*10^{6} \:m^2/s$) $0.43 \: m$ $1 \: m$ $43 \: m$ $103 \: m$

A metallic cube of side $10 \: cm$, density $6.8 \: gm/cc$ is floating in liquid mercury (density $13.6 \: gm/cc$), with $5 \: cm$ height of cube exposed above the mercury level. Water (density $1 \: gm/cc$) is filled over this, to submerge the cube fully. The new height of cube exposed above mercury level is $4.6 \: cm$ $5.4 \: cm$ $5.0 \: cm$ $5.8 \: cm$
