Heat duty to hold tank cargo at setpoint - steady-state loss through tank walls only.
Formula
$$ Q = U \cdot A \cdot \Delta T $$Symbol legend
| Symbol | Meaning | Unit | Source |
|---|---|---|---|
| $U$ | Overall heat-transfer coefficient | W/(m²·K) | tank design |
| $A$ | Heat-transfer surface area | m² | tank geometry |
| $ΔT$ | Cargo − sea/ambient | K | setpoint vs voyage |
