I'm trying so very hard to work out how long it will take to warm up 5 liters of water.
500 watt heating element
Battery = 12V power, 40 Amps
Amount of water = 5 liters
Final Temp = 65 degrees
Ambient Temp = 45 degrees
Ive worked out that it takes 41.86 K joules to heat the required water, so how do i then work out how long it will take to heat up using the specified equipment?
Thanks in advanced!
I believe that if you heat 1 gramme of water by 1 degree celsius you will use 4.2 joules. So to heat 5 litres = 5000 grammes through 20° should take about 5000×20×4.2 = 420,000 joules.
