Water treated as an incompressible liquid is flowing through an adiabatic and horizontal nozzle and remains at a constant temperature (isothermal process). what happens to the following quantities for the water flowing through the device between the inlet and outlet? in each case, justify your answer with basic equations and/or property relations. velocity: a) increases, b) decreases, c) remains constant internal energy: a) increases, b) decreases, c) remains constant enthalpy: a) increases, b) decreases, c) remains constant pressure: a) increases, b) decreases, c) remains constant
