Final answer:
The net heat rate is calculated by dividing the net heat transfer rate in MBtu by the net electric energy output in MWh.
Step-by-step explanation:
The net heat rate is calculated by dividing the net heat transfer rate in MBtu by the net electric energy output in MWh. The net heat transfer rate represents the amount of heat produced by a system, while the net electric energy output represents the amount of electric energy generated.
For example, if the net heat transfer rate is 20 MBtu and the net electric energy output is 5 MWh, the net heat rate would be 20 MBtu / 5 MWh = 4 MBtu/MWh.
Therefore, to calculate the net heat rate, you need to know the net heat transfer rate in MBtu and the net electric energy output in MWh.
