Three kilograms of water undergo a process from an initial state where the water is saturated vapor at 140oC, the velocity is 40 m/s, and the elevation is 5 m to a final state where the water is saturated liquid at 15oC, the velocity is 25 m/s, and the elevation is 2 m. Determine the energy (Φ) at
(a) The initial state,
(b) The final state and
(c) The change in energy (ΔΦ). Take T0 = 25oC, p0 = 1 atm.
