A rigid tank of volume 2m3 initially contains steam at 3bar, 240oC. The tank is connected to a large steam linecarrying steam at 7 bar, 320oC. Steam is allowed to flowinto the tank until 10 kg has been admitted. the steam in the tank is stirred by a paddle wheel with a net energy input to the steamof 2000 kJ. The final pressure in the tank is 5 bar. Determine the heat transfer between the tank and its surroundings,in kJ.
