Regarding the question of calculating the power of electric heating tubes, I will answer you from 2 aspects:
1. If the heating tube has been done, we only need to measure the resistance value of the electric heating tube, and then combine the rated voltage of the electric heating tube to calculate the power, the formula is: power = voltage * voltage / resistance.
2. If the power calculation you are asking about the design of power under a specific working condition, for example, how much power is required for tank heating? Or how much power is needed in the dry-burning oven with an electric heating element? These problems are the power design problems involved.
Regarding the power design, it is necessary to combine the specific working condition information to design:
1.1 The design of the power of the water tank, we may need to know: water volume (kg), temperature difference, heating time, whether there is a thermal insulation layer, whether it is closed heating, etc., after knowing these parameters, you can roughly estimate how much power, need to consult such design, can be connected: Yancheng Feiyu
1.2 The design of the oven power, we may need to know: the size of the oven space (cubic meters), temperature difference, heating time, whether there is a thermal insulation layer, whether it is closed heating, etc., after knowing these parameters, we can roughly estimate how much power.
