Air at \(T_{1}=300 \mathrm{~K}, p_{1}=303 \mathrm{kPa}\), and \(V_{1}=0.5 \mathrm{~m} / \mathrm{s}\) enters the Venturi shown in Fig. P5.43. The air leaves at \(T_{2}=220 \mathrm{~K}\) and \(p_{2}=\) \(101 \mathrm{kPa} ; A_{1}=0.6 \mathrm{~m}^{2}\) and \(A_{2}=1.0 \mathrm{~m}^{2}\). Calculate the horizontal force required to hold the Venturi stationary.
