condensation

Hi

I have Vapour at 52 degrees from a tank (-87.7kPa) going to a Condensor (heat exchange) under vacuum pressure (-87.7kPa).....The Condensor uses water on 1 side to condense vapour on the other side....
1. What temperature does the water need to be to condense the Vapour
2. The vapour produced is 2500kg/hr
3. If evaporating 2500kg/hr of water how much vapour would that produce....would it be 2500kg of Vapour but in a much larger area?

Thank you

Paul

1- colder than the saturation temperature of 38
3- you mean condensing water and you would have to get a heat exchanger large enough to do it
and use the coldest water available.
