12.71 Air flows steadily through a length ( denotes inlet and 2 denotes exit) of insulated constant-area duct. Prop- erties change along the duct as a result of friction. (a) Beginning with the control volume form of the first law of thermodynamics, show that the equation can be reduced to V² m+ 1 = ·m₂ + 2 2 (b) Denoting the constant by ho (the stagnation enthalpy), show that for adiabatic flow of an ideal gas with friction To T constant k-1 =1+ + k=¹M² 2 (c) For this flow does results.

Fluid Dynamics

The study of the flow of gases and liquids, usually in and around solid surfaces, is known as fluid dynamics in physics and engineering. Fluid dynamics, for example, can be used to evaluate the movement of air through an airplane wing or the surface of a vehicle. It can also be used in ship design to increase the speed at which ships pass through water.
