Problem 4: A supply line contains a two-phase mixture of steam and water at 240 °C. To determine the qualityof the mixture a device called a throttling calorimeter is used. In this device a small sample of the two-phasemixture is bled off the line and expanded through a throttling valve to atmospheric pressure (100 kPa). Thetemperature of the steam sample, T2, is measured on the downstream side of the valve. Find the quality of themixture in the supply line for the following two cases:a. T2 = 125 °C.b. T2 = 150 °C.(Note that the two samples are superheated vapor because at the given temperatures, the temperature is abovethe boiling temperature for water at 100 kPa.)Steam - WaterT, = 240 CCalorimeterP= 100 kPaSupply LineFlow
