$2.$A solution is pumped to a vessel $30$m above ground through a $2$ in nominal diameter steel pipe at a rate of $5$m$3/$hr$.$ The length of the pipe is $40$m and contains two elbows and a fully open globe valve. Compute the power requirements for the pump to be used knowing that the density of the solution is $980$kg$/$m$3$ and its viscosity is $1\mathrm{.}5$cP$.$
