Air flows isentropically through a converging nozzle into a receiver in which the absolute pressure is 35 psia. The air enters the nozzle with negligible speed at a pressure of \(60 \mathrm{psia}\) and a temperature of \(200^{\circ} \mathrm{F}\). Determine the mass flow rate through the nozzle for a throat diameter of \(4 \mathrm{in}\).
