What I don´t know is how calculate the "U" because I need some factors which are involved there. In the fouling factor I found 8,8 m2K/W for sea water itself. Should have another for specific biofouling? Another for conduction throw metal.
So problem are numbers, I found this number for seawater...
I´m develping a seawater/water plate heat exchanger.
My problem is that as I´m not a process or mechanical engineer I don´t know some things.
I have to cool water with unespicified flow rate yet, it comes from 70 m high to the plate heat exchanger so I don´t know if it is an impossible question...
