Air is drawn from the atmosphere into a turbomachine. At the exit, conditions are \(500 \mathrm{kPa}\) gage and \(130^{\circ} \mathrm{C}\). The exit speed is \(100 \mathrm{~m} / \mathrm{s}\) and the mass flow rate is \(0.8 \mathrm{~kg} / \mathrm{s}\). Flow is steady and there is no heat transfer. Compute the shaft work interaction with the surroundings.
