(Figure 1). It is proposed that the lower and middle parts (within the Cabora Bassa Riftbasin and the Mana Pools and MidZambezi Basins) of the modern Zambezi River follow the same rift valleys as a major PermoTriassic (Karoo) lake and river system, which originally flowed westwards across the interior of the (Western) Gondwana

Energy content or calorific value is the same as the heat of combustion, and can be calculated from thermodynamical values, or measured in a suitable apparatus:. A known amount of the fuel is burned at constant pressure and under standard conditions (0°C and 1 bar) and the heat released is captured in a known mass of water in a calorimeter. If the initial and final temperatures of the water ...
