0C. If 1 MJ of heat is added, calculate the final
entropy.
How much total energy (in MJ) is contained by a tank holding 287 kg of water if that tank is in the back of a truck that is traveling at 35 m/s at an elevation of 298 m, and the specific internal energy of the water is 60 kJ/kg?
12 kg of steam, initially at 15 bar pressure and 200°C, is contained in a piston-cylinder device. Heat is added at constant pressure until the final temperature of the steam increases to 350°C. Calculate the amount of heat added.
A rigid tank initially contains 0.32 kg steam at 4 MPa, superheated by 350°C. Now the steam loses heat to the surroundings and the cooling of tank continues until the cylinder contains water at 90°C. Determine; (a) the final pressure and the quality (if mixture), (b) the boundary work, (c) the amount of heat transfer (d) and the total entropy generation if the Tsur=20 °C.
