2. A supply line carries a two-phase liquid-vapor mixture of steam at 20 bar. A small fraction of the flow in the line is diverted through a throttling calorimeter and exhausted to the atmosphere at 1 bar. The temperature of the exhaust steam is measured as 160°C. Determine the quality of the steam in the supply line.
