Air with a mass flow rate of 2.3 kg/s enters a horizontal nozzle operating at steady state at 450 k, 350 kpa, and velocity of 3 m/s. at the exit, the temperature is 300 k and the velocity is 460 m/s. using the ideal gas model for air withconstant cp =1.011 kj/kg k, determine

- decrease the number of plants and animals living in the water.

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.
