What is interesting to note is that heavier than water fluids will spray less volume of fluid through a spray but the weight of the spray will still be heavier. This can be seen from the equation above as the flow rate (volume) is reduced by a 1/root SG factor where as the fluid weight of that spray will obviously be increased by a factor of SG2.

The makeup water is sprayed into the spray shroud through a spray nozzle. At the same time steam is also released into it. Spraying of water increases the contact surface area of water with the steam. This leads to a faster heat transfer rate. Thus, water gets heated quickly and many non-condensable gases are liberated fast.
