1. Superheated Steam enters a turbine with a pressure of 10 bar and a temp of 300 degrees celcius, and exits with a pressure of 0.046 bar. As the steam flows through the turbine it undergoes adiabatic expansion according to the law pv to the power 1.131 = constant
From Steam tables I have to calculate :
a) specific volume of steam at the turbine input and output (I assume that's just v straight from the Superheated tables at the relevant pressures ?)
b) Saturated vapour specific volume for the steam output pressure and state the steam condition ?
c) dryness fraction of the steam at the turbine exit ?
d) theoretical specific work output of the turbine ?Can anyone help me on the above please as I've scoured the internet for a solution and got part of the way in understanding but then can't follow how the things are found on the steam tables and what equations are used - any help would be greatly appreciated
