2. Wet steam flows in a pipe at a pressure of 700kPa. To check the quality, the wet steam is expanded adiabatically to a pressure of 100kPa in a separate pipe. A thermo-couple inserted into the pipe indicates the expanded steam has a temperature of 125C. 2.1. What was the quality of the wet steam in the pipe prior to expansion? (5) 2.2. Find the power output of an insulated generator that uses 700kg/hr of steam at 10atm and 500K. The steam exits at 1atm and is saturated. 2.3. Oxygen at 150K and 41.64atm has a tabulated specific volume of 4.684cm3/g and a specific internal energy of 1706J/mol. Calculate the specific enthalpy of oxygen in this state
