1 Quick Equation about heat Flow

1 Quick Equation about heat Flow.

I don’t know how to handle this Science question and need guidance.

The thermal resistance R of insulation is given by the expression: Q h = A (T high – T low)/R, where Q h is the flow rate of heat (btu/hr) across a wall with cross-sectional area A (ft 2). The heat flow from the side of the wall with the higher temperature T high (o F) to the side with the lower temperature T low (o F). Estimate the flow rate of heat across a wall that is 8.0 ft high and 10.0 ft long. The temperature difference on a winter day is: T high – T low = 50 oF, and the R-value is 13 [oF – ft 2/(btu/hr)
