[10 points] The air speed measurement venturi has a stagna shown below. The speed of air at the inlet is one third of the velocity at the outlet. The density of air is assumed as $1.2\mathrm{kg}/{\mathrm{m}}^3$. The manometer tube reads $10\mathrm{cm}$ pressure difference between the two ports (stagnation and static). If the outlet pressure is $98\mathrm{kPa}$, and the diameter of section 1 is $25\mathrm{cm}$. determine the following: A. The outlet velocity in $\mathrm{m}/\mathrm{s}$. [4 points] - B. The inlet velocity in $\mathrm{m}/\mathrm{s}$. [2 points] $?1/2$ C. The mass flow rate of air. [2 points] $?1/1/2$ D. The pressure at the inlet in $\mathrm{kPa}$. [4 points] - 1
