1. The problem statement, all variables and given/known data An amount of saturated steam at a pressure of 10 Bar, undergoes an isentropic (constant entropy) expansion. The final temperature is 30C. Find the final specific enthalpy and specific volume. 2. Relevant equations Saturated Steam tables, Linear Interpolation methods? No real equations of sort. 3. The attempt at a solution By using the tables; at 10 bar; sf ( entropy) = 2.138 kJ/kg K v (specific volume) = 0.1944 m3/kg at 30C; sf ( entropy) = 0.436 kJ/kg K v (specific volume) = 32.93 m3/kg I've been staring into space with the question, not sure what to do. The final answers are given as 1990 kJ/kg for specific enthalpy and 25.28m3/kg for specific volume. Thanks for any help!
