Design of the Automatic Voltage Regulator,Engineers have a prime concern with the production of mechanical work. Since all processes are irreversible in practice, the capacity to perform work is continually being degraded by virtue of the unwanted heat transfers which occur because of viscous friction and large temperature differences between the working fluid and its environment.

Steady Flow Processes-Vapours,The nozzles of a steam turbine receive steam at 3 bar and 150 °C with negligible velocity. The steam expands adiabatically through the nozzles and leaves at 1 bar with a dryness fraction of 0.96. Calculate

Steady Flow Processes-Energy and Momentum,In this chapter a new fundamental concept appears — namely momentum — and in addition to the principles of conservation of mass and energy previously encountered we have to use the third principle — conservation of momentum which is embodied in Newton’s laws of motion.
