How to calculate the power of the electric heating tube
The calculation of the power of the electric heating tube is mainly analyzed from two aspects:
1. If the heating tube has been completed, 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. How much power is required for heating the water tank? Or how much power electric heating tube do you need in a dry-burning oven? These problems are related to power design problems.
Regarding the issue of power design, it is necessary to design based on the specific working condition information: for the design of the power of the water tank, we need to know: the amount of water (kg), the temperature difference, the heating time, whether there is a thermal insulation layer, whether it is closed for heating, etc. After knowing these parameters , you can roughly estimate the power. For the design of the oven power, we need to know: the size of the oven space (cubic meters), the temperature difference, the heating time, whether there is a thermal insulation layer, whether it is closed for heating, etc. After knowing these parameters, we can roughly estimate the power.
