Macmillan L Nitrogen gas enters a 0.450 m diameter pipe at 30.0 °C, 2.60 atm (absolute), and 6.30 m/s. The pipe rises 24.0 ft and then falls 99.0 ft. The nitrogen gas exits the pipe at 30.0 °C and 1.10 atm (absolute). The ultimate goal is to find AEK and AĖp in the process. Assume N₂ behaves ideally. 4 V₁ = What is V₁, the volumetric flow rate of nitrogen gas into the pipe section? What is m, the mass flow rate into the pipe? ーー z, ft T, °C P, atm (absolute) u, m/s z, ft T₂ °C P, atm (absolute) u₂ m/s m³/s

Question 2. Solve with detailed solutions please. Thank You

You have a tank that is 0.01 m^3 and is initially evacuated. You then hook this up to a line that supplies N2 at a pressure of P_1 = 5 bar and a T_1 = 350 K. The tank fills adiabatically (you can assume there is no heat flow to the walls of the tank), and the filling ends when no more N2 flows into the tank. Find a) the final pressure of the gas in the tank, and b) the final temperature of the gas in the tank. You can assume N2 is an ideal gas with a CP* = 29 J/mol K. NOTE: Mainly I am confused on how the evacuated tank factors into the work for b). What I did was use the ideal gas formula to find a value for N2*T2 (601.395) but I am no longer certain how to continue in the work. I was assuming the practice question had meant the temperature of the tank was 0 initially but it leads to a negative mole value. For a) I got 5 bar, arguing the flow would stop when the pressure of tank and line are equal
