Question:
Air enters a smooth, insulated $3 \mathrm{~cm}$ diameter duct with stagnation pressure and temperature of $200 \mathrm{kPa}, 500 \mathrm{~K}$, and a velocity of $100 \mathrm{~m} / \mathrm{s}$. Compute (a) the maximum duct length for these conditions, (b) the mass flow rate for a duct length of $15 \mathrm{~m}$ and $30 \mathrm{~m}$. Take $f=0.02$.
Fantastic news! We've Found the answer you've been seeking!
Step by Step Answer:
To solve this problem we need to use the isentropic relations to determine the Mach number at the exit of the duct and then use the Fanno flow equations to determine the pressure loss and the maximum ...View the full answer
