This problem presents a comparison of the work required in adiabatic pumps and compressors. a. Saturated water vapor enters a steady-state compressor at P =1bar. Estimate the work required to compress this vapor up to P=10 bar and T=4000C. b. Saturated liquid water at P=1 bar enters a pump. Estimate the work required to pump the liquid up to P=10 bar, and estimate the temperature of the exiting liquid.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
