Want to discuss a matter here. If steam remains saturated during compression, how to calculate the power consumption for that by using steam table. Suppose, saturated steam has been compressed from pressure level A to pressure level B and it remained saturated during and after compression. We have steam table before us and we know the gross enthalpy of steam a level A and level B. Now, to calculate the power consumption with 100% efficiency, do we deduct gross enthalpy of steam at level A from gross enthalpy of steam at level B or there is some other method to be applied here?
