Water is boiling in two different size pots. One has a diameter of 0.3 m and the other has a diameter of 0.1 m. If they both have a surface heat flux of 700 kW/m2 , how much water has evaporated in 2 min in each case? If the larger pot has twice as much water as the smaller pot, what is the ratio of total time for all the water to evaporate in the larger pot compared to the smaller pot?
