Question

Chemical Engineering:

Nitrogen gas enters a 0.320-m diameter pipe at 39.0°C, 2.30 atm (absolute), and 5.60 m/s. The pipe then rises 17.0 ft and then falls 87.0 ft. The nitrogen gas exits the pipe at 39.0°C and 1.30 atm (absolute). You ultimately would like to find ΔEk and ΔEp in the process. Assume N2 behaves ideally.

What is V1, the volumetric flow rate of nitrogen gas into the pipe section?______m^3/s

What is the mass flow rate into the pipe?______kg/s

What is the average velocity of N2 leaving the pipe section?______m/s

What is the change in kinetic energy of the gas between the end and the start of the pipe section?________J/s

What is the change in potential energy of the gas between the end and the start of the pipe section?______J/s
