Question

Flow enters a constant-area insulated duct with a Mach number of 0.60 static pressure of 150 kPa, and static temperature of 300K. Assume a duct lenght of 45 cm, duct diameter of 3 cm, and a friction coefficient of 0.02. Determine the Mach number, static pressure, and static temperature at the dict outlet. 8. Flow enters a constant-area, insulated duct-111m with a Mach number of} 0.60, static pressure of 150 kPa, and static temperature of 300 K. Assume a duct length of 45 cm, duct diameter of 3cm, and a friction coefficient of 0.02 length of 45 cm, duct diameter of 3cm, and a friction coefficient of 0.02 Determine the Mach number, static pressure, and static temperature at the duct outlet.

Explanation / Answer

By using flowfanno function we can solve this problem

Fanno paramater = (.02*45) / 3 = .3

Outlet mach number = 0.7093

Outlet temp 292.2018 k

Outlet static pressure is 125.2332 kPa
