Air flows isentropically through a converging nozzle into a receiver where the pressure is \(250 \mathrm{kPa}\) absolute. If the pressure is \(350 \mathrm{kPa}\) absolute and the speed is \(150 \mathrm{~m} / \mathrm{s}\) at the nozzle location where the Mach number is 0.5 , determine the pressure, speed, and Mach number at the nozzle throat.
