What is a Temperature Gradient? (with picture)

WebOf course, if the heat flow is not constant with depth, the temperature must be changing. The temperature at any point changes at a rate proportional to the local gradient in the heat flow: ∂ ∂ρ ∂ ∂ T tC Q P z = − 1 units K s kgm J kgK Jms m: / / = ()− 1 3 2 So, if there is no gradient in the heat flow (∂Q/∂z = 0), the ...

"WebThe temperature gradient for the window in Example 1 is This equation can be integrated to give where x is in meters and T is in degrees Celsius. If the inner face of the window is taken to be at x = 0, the constant of integration must equal the temperature at that position. Thus Tinner = 68°F = 20°C gives " - How to determine the temperature gradient
