QUESTION:

Air at \(600 \mathrm{kPa}, 330 \mathrm{~K}\) enters a well-insulated, horizontal pipe having a diameter of \(1.2 \mathrm{~cm}\) and exits at \(120 \mathrm{kPa}, 300 \mathrm{~K}\). Applying the ideal gas model for air, determine at steady state (a) the inlet and exit velocities, each in \(\mathrm{m} / \mathrm{s}\), and (b) the mass flow rate, in \(\mathrm{kg} / \mathrm{s}\).
