- TL;DR Summary
- I have a system that requires 2405 kilojoules to vaporise 1 kilogram of water. I have a mass flow rate of 0.0129 kg per second. How many watts are required per second to sustain the required vaporisation rate.
My understanding is that electrical devices are rated in watts which is really watts per second. For instance if a peltier module is rated at 5 watts it will use 5 watts per second. I had thought that it should be simple to convert kilojoules to watts but everywhere I’ve looked i can only find kilojoules to watt hour conversion yet I can find calculations to convert joules to watts in turbines ( power output ). Is it as simple as converting kilojoules to watt hours and then dividing by 3600 to get back to watts required per second.
