please answer accurately and completely and i will thumbs up

Carbon dioxide flows adiabatically through a 3-in Schedule 40 pipe. At the entrance of the pipe (point a) the velocity is 350 ft/s, with Ta=120F and Pa = 30 psia.

(a) What is the maximum possible length of the pipe?

(b) What are the pressure, stagnation temperature, linear velocity, and mass velocity of the gas at the end of the pipe at maximum length?
