Question

Nitrogen flows at a velocity of 54 m/s into the inlet of a 10.2 cm pipe. The pressure and temperature at the inlet are 301.5 kPa and 24 °C, and at the outlet, they are 183 kPa and 18 °C. The gas constant for Nitrogen is 0.2968 kJ/kg/K, the specific heat is 1.039 kJ/kg/K, and the density is 1.25 kg/m³. Find the entropy generation rate in kW/K and 3 sf.

a-flow-of-nitrogen-01-mathrmkg-mathrms-comes-out-of-a-compressor-stage-at-500-mathrmkpa-500-mathrm-3

A flow of nitrogen, $0.1 \mathrm{~kg} / \mathrm{s},$ comes out of a compressor stage at $500 \mathrm{kPa}, 500 \mathrm{~K}$ and is now cooled to $310 \mathrm{~K}$ in a counterflowing intercooler by liquid water at $125 \mathrm{kPa}, 15^{\circ} \mathrm{C}$ that leaves at $22^{\circ} \mathrm{C}$. Find the flow rate of water and the total rate of entropy generation.

Saturated liquid nitrogen at $600 \mathrm{kPa}$ enters a boiler at a rate of $0.005 \mathrm{~kg} / \mathrm{s}$ and exits as saturated vapor. It then flows into a superheater, also at $600 \mathrm{kPa}$, where it exits at $600 \mathrm{kPa}, 280 \mathrm{~K}$. Assume the heat transfer comes from a $300 \mathrm{~K}$ source and find the rates of entropy generation in the boiler and the superheater.
