The rocket shown in Fig. P5.61 is held stationary by the horizontal force, \(F_{x}\), and the vertical force, \(F_{z}\). The velocity and pressure of the exhaust gas are \(5000 \mathrm{ft} / \mathrm{s}\) and \(20 \mathrm{psia}\) at the nozzle exit, which has a cross section area of \(60 \mathrm{in.}^{2}\). The exhaust mass flowrate is constant at \(21 \mathrm{lbm} / \mathrm{s}\). Determine the value of the restraining force \(F_{x}\). Assume the exhaust flow is essentially horizontal.
