Module 7: Finite Control Volume Analysis: Conservation of Energy

The conservation of energy for a control volume can be derived from  the first law of thermodynamics, which states the time rate of increase of the total stored energy of the system = net time rate of energy added by heat transfer into the system + net time rate of energy addition by work transfer into the system.

Student Learning Outcomes: After completing this module, you should be able to:
