Calculate tank heating time t = m × Cp × (T₂ - T₁) / Q from liquid mass, specific heat, target temperature rise, and heat supply rate. Apply to batch reactor scheduling, melting operations, and heated tank operation planning.
Tank Heating Time Calculator
Calculates the time required to heat a liquid batch to a target temperature. This simplified calculation assumes ideal insulated conditions; actual processes should account for heat losses.
Formula
t = m × Cp × (T₂ − T₁) / Q_heater
m: Liquid mass [kg]
Cp: Specific heat [kJ/kg·K] (water: 4.18, organics: 1.5–2.5)
No. This calculates the ideal heating time assuming all supplied heat goes into raising the liquid temperature. In practice, heat losses to surroundings extend the actual heating time. Apply an appropriate margin (typically 10-30%).
Can I use this for batch reactor heating?
Yes, for estimating heat-up time in batch reactors. However, if a chemical reaction occurs during heating, the heat of reaction must be accounted for separately (exothermic reduces time, endothermic increases it).
These results are preliminary estimates for screening-level design use. They do not replace detailed engineering, code compliance verification, or vendor-certified calculations.
