SUMMARY
The discussion clarifies that total mechanical energy can be expressed as energy per unit mass, which simplifies the calculations by eliminating the mass variable. The equation for total mechanical energy is redefined as gh + 0.5v² instead of mgh + 0.5mv². This approach is particularly useful for analyzing systems like hydro plants, where energy per unit mass allows for easier calculations of energy flow rates. The key takeaway is that the mass is effectively normalized to one, allowing for a more straightforward analysis of mechanical energy.
