1.4 1kg of a fluid expands reversibly according to a lincar law from 4.2 bar to 14 bar; the initial and final volumes are 0.004 m' and 002 m. The fluid is then cooled reversibly at constant pressure, and finally compressed reversibly according to a law pe = constant back to the initial conditions of 4.2 bar and 004 m. Calculate the work done in cach process and the net work of the cycle. Sketch the cycle on a p- diagram (-4480 N m: +1120 N m, + I845 N m, -151S Nm)

1.) 0.44 kgm of air at 1800C expands adiabatically to three times its original volume and during the process, there is a decrease in temperature to 150C. Find the work done on the substance.
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
CA ges contained in a cylinder is compressed from 1 MPa and 0.05 m² to 2 MPa. Compression is governed by pV4 = constant. Internal energy of gas is given by U = 7.5 pV - 425, kj where p is pressure in kPa and V is volume in m'. Determine heat, work and change in internal energy assuming compression process to be quasistatic. Also find out work interaction, if the 180 kJ of heat is transferred to system between same states. Also explain, why is it different from above.
