3 cards from this section. Quick, good the night before a test.
Define Higher Heating Value in your own words.
Think of all heat released during combustion.
What is Lower Heating Value?
Consider what happens to the water vapor.
What does HHV stand for?
Focus on the use of 'Heating'.
True or False: The LHV includes the latent heat of condensation.
Recall the differences between LHV and HHV.
If a fuel system's efficiency is reported at 85% using LHV, calculate the efficiency if HHV is considered instead.
Consider your efficiency values and how they relate!
A technician is measuring the heating value of wood. If the wood has a HHV of 20 MJ/kg and LHV of 19 MJ/kg, calculate the heat loss in MJ/kg.
Subtract the two values for the difference!
