Question
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 AEp in the process. Assume N₂ behaves ideally. What is V₁, the volumetric flow rate of nitrogen gas into the pipe section? V₁ = 1 What is m, the mass flow rate into the pipe? z, ft T, °C P, atm (absolute) u, m/s z, ft T₂ °C P, atm (absolute) u, m/s m³/s
