Consider subsonic airflow through a 10-cm- diameter adiaba0c duct with inlet condi0ons of T1 = 330K, P1 = 180kPa, and Ma1 = 0.1. Taking the average fric0on factor to be 0.02,
(a) determine the duct length required to accelerate the flow to a Mach number of unity. Also (b) calculate the duct length at Mach number intervals of 0.1, and
(c) plot the duct length against the Mach number for 0.1 ≤ ma ≤ 0.1;
(d) Discuss the results in (c) above.
