Standard calculation method without weighting
Use the formula above, replacing W to 1 for the standard calculation.
Regardless of the shape of the tank, average temperature is calculated by using the actual
formula:
(T1 + T2 + T3) / Number of elements in liquid phase = Average temperature
(3.5 °C (38.3 °F) + 3.0 °C (37.4 °F) + 2.0 °C (35.6 °F)) / 3 = 2.83 °C (37.1 °F)

T5 (Element No.5): 4.5 °C (40.1 °F)
2
T4 (Element No.4): 4.0 °C (39.2 °F)
3
T3 (Element No.3): 2.0 °C (35.6 °F)

T2 (Element No.2): 3.0 °C (37.4 °F)
5
T1 (Element No.1): 3.5 °C (38.3 °F)
Advanced calculation method with weighting
Average temperature is calculated by adding a corrective factor for unequal volume
distribution. Use the formula below and input W to volume ratio for the advanced
calculation.
Formula: (T1 * W1 + T2 * W2 + T3 * W3) / (W1 + W2 + W3) = Average temperature
Formula: (3.5 °C (38.3 °F) x 2 + 3.0 °C (37.4 °F) x 3 + 2.0 °C (35.6 °F) x 4) / (2 + 3 + 4) =
2.67 °C (36.8 °F)

2.67 °C (36.8 °F)
