A steel pot (diameter 200 mm) is fully filled with water (2 kg of water) and the water is maintained at a constant temperature of 40°C by supplying heat from an electrical tabletop burner.
Assume the heat supplied from the burner is 0.20 kWh (kW per hour). Let us neglect the heat losses.
The pot is kept open to the surrounding (room). Hot air with a temperature of 60°C and a velocity of 1.5 m/s is blown across the water surface of the pot to assist the evaporation process.
How can the amount (mass) of water evaporated from the pot after 1 hour be calculated? What are the formulae to be considered to calculate the evaporated amount of water under forced convection?
