Oil Tank Heat Loss

Overview

Engineering reference data for Oil Tank Heat Loss in thermodynamics.

Key Formulas

First Law

$\Delta U = Q - W$

Energy is conserved — heat added minus work done.

Ideal Gas Law

$PV = nRT$

Relates pressure, volume, and temperature of an ideal gas.

Heat Transfer

$Q = mc\Delta T$

Sensible heat transfer.

Carnot Efficiency

$\eta = 1 - T_C/T_H$

Maximum efficiency between two temperatures.

Variables

Heat Loss Coefficients for Oil Tanks

The heat loss from oil tanks varies based on whether the tank is insulated (lagged) or not, and its exposure to environmental conditions. The following table summarizes the heat loss coefficients for different oil temperature ranges.
