Strain energy

The term strain indicates the variation in an object's length, area, and volume when the object is subjected to an external force. The external force may be of normal, shear, moment, torque, etc. The strain in an object depends on the types of external force and cross-section of the object. Mathematically, the evaluation of strain can be obtained with the help of elastic constants.

Two-thirds of the energy content of fuel entering a 1,000-MWe nuclear power plant is removed by condenser cooling water that is withdrawn from a local river (there are no stack losses, as it the case for a fossil fuel-fired plant). Note, the 1,000-MWe refers to the actual electricity generated and sent to the power lines, after waste heat is taken away from cooling water. The river has an upstream flow of 100 m3/s and a temperature of 20 ̊ C.(a) If the cooling water is only allowed to rise in temperature by 10 ̊C, what flow rate from the river would be required? (b) How much would the river temperature rise as it receives the heated cooling water?
