Q.) A piston-cylinder device contains air at initially 1000 kPa and 200°C. The airis first expanded isothermally to 600 kPa, 0.2 m' then compressed Polytropicallywith an unknown Polytropic exponent to the initial pressure and double the initialvolume (V1), and finally expanded at a constant pressure to the initial state. Drawthe PV diagram of the cycle and then determine:1. The boundary work of the entire cycle (W). Is this a practical cycle?II. Internal energy change (AU) during the polytropic process.III. Heat (Q) during the isobaric process.

An art school specializes in metal sculptures and to save money and space they don't have a metal workshop with traditional power tools and cutting torches. To make the sculptures the students gather scrap metal and use a specialized steamer that heats the already thin metal enough to easily bend and can be used inside around other flammable materials as it is steam powered. The steamer creates the steam and then heats it through a funnel from 100 to 450 °C. Use steam tables to find what the heat input in Watts (W) of the funnel is if a continuous stream of steam at a rate of 50 kg/s undergoes the heating process at a constant pressure. Assumption: We are assuming that the P(bar) of saturation is at 0.1 for our steam tables
