Chemical Engineering Thermodynamics 2- A rigid tank contains a hot fluid that is cooled while being stirred by a paddle wheel. Initially, the internal energy of the fluid is 300 kJ. During the cooling process, the fluid loses some heat, and the paddle wheel does 250 kJ on the fluid. Finally, the internal energy of the fluid becomes 500 ki, Determine the work done by the paddle wheel. (Write only the answer such as ....kj) Qout= ? U=300 kj U=500 kj Fluid Win=250 kj MA
