$5\mathrm{.}1\mathrm{.}23$ Air at standard conditions enters the compressor shown in Fig. P$5\mathrm{.}1\mathrm{.}23$ at a rate of $0\mathrm{.}28\frac{m^3}{s}.$ It leaves the tank through a $0\mathrm{.}03$ m $-$diameter pipe with a density of $1,50k\frac{g}{m^3}$ and a uniform speed of $213\frac{m}{s}.($a$)$ Determine the rare $(k\frac{g}{s})$ at which the mass of air in the tank is increasing or decreasing. $($b$)$ Determine the average time mate of change of air density within the tank.
