Question
Chapter 6, Problem 6.3P
(a)
Interpretation Introduction
Interpretation:
Pressure, temperature, and Mach number of air is to be plotted against the flow length.
Concept Introduction:
The flow behavior of compressible fluids such as air is determined by Mach number. It refers to the ratio of speed of fluid to that of sound under flow conditions. Hence, when speed of fluid is equal to that of sound, Mach number is unity. This condition is known as sonic discharge. If Mach is less than unity, then such flows are called subsonic discharges. Under these circumstances, Mach number is related with the conduit specifications depending upon the
(b)
Interpretation Introduction
Interpretation:
Pressure, temperature, and Mach number is to be plotted against flow length for supersonic flow.

The flow behavior of compressible fluids such as air is determined by Mach number. It refers to the ratio of speed of fluid to that of sound under flow conditions. Hence, when speed of fluid is equal to that of sound, Mach number is unity. This condition is known as sonic discharge. If Mach is greater than unity, then such flows are called supersonic discharges. Under these circumstances, Mach number is related with the conduit specifications depending upon the thermodynamic state of fluid.
