There are received 90000 kg/h of steam at 2.15 mpa, 480°c by a rankine engine; exhaust occurs at 0.10 mpa. For the engine find (a) W (b) m and (a) e. For the cycle find (a) W and (b) e.

How do I do this questions in steps? Stuggling with how to find the isentropic work for the efficiency of the turbine. Please have written out or neat solutions that arent copied and pasted math.

3. An adiabatic compressor takes argon from 100 kPa, 300 K to 2000 kPa. The compressor efficiency is 80%. (a) Find the outlet temperature (K) and the work (kJ/kg) (b) Find the entropy generation (kJ/kg-K)
