An inventor is interested in patenting a device. The device takes in 100 kg/min of H2S under ideal conditions. The gas enters the device at 600 K and 4.0 bar and leaves the device at 300 K and 1.0 bar. This process is supposed to produce 5000 J/min of work and requires an undisclosed amount of heat transfer, with a heat sink that is at a constant temperature of 300 K. Is the device patentable, i.e. does it obey the First and Second Laws of Thermodynamics?

Problem 1 (20 points) A compressor operating at steady state takes in 45 kg/min of methane gas (CH4) at 1 bar, 25°C, 15 m/s, and compresses it with negligible heat transfer to 2 bars, 360 K, 90 m/s. Potential energy effects are negligible. Using the ideal gas model, calculate the power required, in kW.
