Air at po 5 1.4 bar, To 5 280 K expands isentropically
Chapter 9, Problem 9.125(choose chapter or problem)
Air at \(p_{\mathrm{o}}=1.4 \mathrm{bar}, T_{\mathrm{o}}=280 \mathrm{~K}\) expands isentropically through a converging nozzle and discharges to the atmosphere at 1 bar. The exit plane area is \(0.0013 \mathrm{~m}^{2}\). Assume k = 1.4.
(a) Determine the mass flow rate, in kg/s.
(b) If the supply region pressure, \(p_{0}\), were increased to 2 bar, what would be the mass flow rate, in kg/s?
