(b) A flow the velocity of 116 m/s and the static temperature of -20°C enters a pipe with the constant diameter of 1.75 cm and the fanning friction coefficient of 0.011. Consider air as perfect gas with g = 1.4.
i) Find the maximal growth of the entropy of air from the reference state.
ii) Draw the h-s diagram for the flow (include the subsonic branch)
iii) Find the maximal length of the pipe
iv) If the length of the pipe exceeds the maximal length by 50%, sketch the pressure and the Mach number variation along the pipe.
