Engineering Calculator
Heater Wattage Calculator
Calculate the minimum heater power required to heat a mass to operating temperature within a defined time window, including a configurable heat loss factor.
Formula: W = (m × Cp × ΔT × 1000) / t_seconds × (1 + heat_loss_factor)
where m = mass (kg), Cp = specific heat (kJ/kg·°C), ΔT = temperature rise (°C), t = time (s)
where m = mass (kg), Cp = specific heat (kJ/kg·°C), ΔT = temperature rise (°C), t = time (s)
