Standard calculation method

Regardless of the shape of the tank, average temperature is calculated using the following

formula:
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)

 32

Standard calculation method for liquid temperature

Element No.5: 4.5 °C (40.1 °F) (T5)

Element No.4: 4.0 °C (39.2 °F) (T4)

Element No.3: 2.0 °C (35.6 °F) (T3)

Element No.2: 3.0 °C (37.4 °F) (T2)

Element No.1: 3.5 °C (38.3 °F) (T1)

Advanced calculation method

Average temperature is calculated by adding a corrective factor for unequal volume

distribution.
Formula: (T1*V1 + T2*V2 + T3*V3) / (V1 + V2 + V3) = Average temperature

Parameters that are related to V = additional volume factors are determined in VH53,

54 and 55.
