Air is flowing through a 6-cm-diameter adiabatic duct with inlet conditions of V 1 = 120 m/s,
Question:
Air is flowing through a 6-cm-diameter adiabatic duct with inlet conditions of V1 = 120 m/s, T1 = 400 K, and P1 5 100 kPa and an exit Mach number of Ma2 = 1. To study the effect of duct length on the mass flow rate and the inlet velocity, the duct is now extended until its length is doubled while P1 and T1 are held constant. Taking the average friction factor to be 0.02, calculate the mass flow rate, and the inlet velocity, for various extension lengths, and plot them against the extension length. Discuss the results.

Step by Step Answer:
To calculate the mass flow rate and inlet velocity for various extension lengths of the duct well first find the conditions at the exit of the original duct length L1 with Mach number Ma2 1 Then well ...View the full answer
