A cylindrical body $($volume $V_K,$ density ${}_W)$ suspends in a vertical pipe $($diameter $D)$ through a water flow. The process can be calculated without friction. The pressure at the cross section $1$ and $2$ is constant but not equal.

${}_W=1000k\frac{g}{m^3}$

$D=0,1m$

$d=0,03m$

$V_K=40*{10}^{-6}{m}^3$

$g=9,81\frac{m}{s^2}$

$L=0,3m$

$U=2,73\frac{m}{s}$

Sketch the control volume and mark the forces on the surfaces.

Calculate the pressure difference between $1$ and $2.$

Calculate the density of the body.

i wanI want answer and sketch

please do this urgently
