In a Rankine cycle, the work done by the turbine can be found by multiplying the mass flow rate by the difference in this quantity across the turbine.
In a Rankine cycle, the work done by the turbine can be found by multiplying the mass flow rate by the difference in this quantity across the turbine. The derivative of this quantity with respect to temperature gives the constant-pressure heat capacity. This quantity is held constant during a throttling process. The change in this state function, defined as the internal energy plus the product of pressure and volume, can be summed over component reactions to obtain this quantity for the total reaction. The change in this quantity is positive for an endothermic reaction. For 10 points, name this quantity whose change can be calculated using Hess's Law, symbolized H.
