Heat Loss Calculator

Formula

The formula to calculate the heat loss is:

\[ q = (U \cdot A) \cdot \Delta T \]

Where:

\( q \) is the heat loss (W)
\( U \) is the heat transfer coefficient (W/m²·K)
\( A \) is the area (m²)
\( \Delta T \) is the temperature difference (K or °C)

Heat Loss Definition

Heat loss is defined as the total energy lost due to the transfer of heat between a hotter surface and a colder ambient area. It is an important factor in understanding energy efficiency and thermal insulation in buildings and other structures.

Example Calculation

Let's assume the following values:

Heat Transfer Coefficient (U) = 1.5 W/m²·K
Area (A) = 50 m²
Temperature Difference (ΔT) = 20 °C

Using the formula to calculate the heat loss:

\[ q = (1.5 \cdot 50) \cdot 20 = 1500 \text{ W} \]

The heat loss is 1500 W.
