Approximate calculation of the needed power

For all induction - Heating applications where work pieces with certain dimensions and mass in a required period of time to a given
Temperature have to be heated, you can use the formula below to calculate the estimate power of the needed Generator:

P = m - c - ΔT / t

P Generator power [kW]
m Mass Work piece [kg]
c special Heat quantity [kW s / kg K]
ΔT Temperature difference [K] (End temperature - Starting temperature)
t Heating time [s]
