8 kg of steam is contained a piston-cylinder as shown in the figure below, 75 kJ of heat is transferred to the steam causing it to expand from initial state where the specific internal energy is u, =2710.0 kJ/kg to final state where u, = 2660.5 kJ/kg. During the process, a 20 kJ of paddle whee! work is also added to the steam. Assuming that there is no significant change in kinetic and potential energies, determine the work transferred by steam to the piston during the process, in kJ. .4 %3D Wr.- 20 kJ 6 kg of steam Q= 75 k

8 kg of steam is contained a piston-cylinder as shown in the figure below, 75 kJ of heat is transferred to the steam causing it to expand from initial state where the specific internal energy is u,=2710.0 kJ/kg to final state where u, = 2660.5 kJ/kg. During the process, a 20 kJ of paddle whee! work is also added to the steam. Assuming that there is no significant change in kinetic and potential energies, determine the work transferred by steam to the piston during the process, in kJ. .4 Wu- 20 kJ 6 kg of steam Wpron Q= 75 kJ
