Nitrogen gas enters a 0.500m diameter pipe at 27.0C, 3.00atm (absolute), and 4.90m/s. The pipe rises 40.0ft and then falls 75.0ft. The nitrogen gas exits the pipe at 27.0C and 1.60 atm (absolute). The ultimate goal is to find Ek and Ep in the process. Assume N2 behaves ideally. What is V1, the volumetric flow rate of nitrogen gas into the pipe section? V1 What is m, the mass flow rate into the pipe? m What is u2, the average velocity of N2 leaving the pipe section? u2 What is Ek, the change in kinetic energy of the gas between the end and the start of the pipe section? Ek What is Ep, the change in potential energy of the gas between the end and the start of the pipe section? Ep
