Mechanical Engineering

Air flows in a pipe with a diameter, D=50 mm. The inletconditions are: M1 = 3; total pressure,
P01 = 1000 kPa absolute; and temperature, T1 = 550 K. The frictioncoefficient is, f = 0.004. The exit Mach number decreases with thelength of the pipe.

Plot the following while the exit Mach number to bechanged from 2.5 to 0.99 with decrements of?M=0.01:
a) L, length of the pipe that is going to give the desiredexit Mach number,

b) the P2, pipe exit pressure,

c) T2, pipe exit temperature, and

d) P02, pipe exit total pressure.

Make sure that each plot has a title and that the axes of theplots are labeled. Assume that the flow is steady and adiabatic.Use ?=1.4 and Cp = 1004.5 J / ( kg . K ).
