WebFor a steady flow Q of water in a vertical hole, a uniform geothermal gradient is equivalent to a heat source, existing at a large distance from the well; this heat source provides, to the flow Q of water, a constant radial heat flux per depth meter of the rock formation, with: Ti ( z) = temperature in the formation at depth z, far away from ... WebGeothermal gradient. Temperature is probably the parameter that most people associate with when they are introducted to the term heat flow. More importantly then temperature itself though is the change in temperature over a given distance. If we consider two points, T 1 and T 2, over a given distance, Δ z, the thermal gradient is defined as δ ...
