Using the diagram below establish equations for all the energy entering and leaving the system. i. Identify all the sources of energy entering and leaving the system below, for each term produce an equation for the amount of energy using the algebraic terms below. ii. Use the first law of thermodynamics to construct a steady flow energy equation for this system. iii. Make W the subject of the equation iv. Make
