How would I calculate the rate that water would boil off? I've done a lot of looking into and found an equation but it doesn't seem quite right. What I found states that the KJ/h delivered to the water divided by the latent heat energy gives you the amount of water that will boil off. I tried this but I got a very low amount (.05 kg/h).

I'm boiling 4kg of water in an area that's ambient temperature is 60C under reduced pressure (about 30 torr) in a closed system. The boiling point is 30C and the latent heat energy is about 2438 KJ/kg at this pressure. Is the boiling rate just very slow or should I be using a different equation? Or will I just have to test the system and find out for myself?
