Hi trnsys users
I have a problem to verify the "Overall heat transfer coefficient of exchanger" of type 5b. I m using type 5b in a lake and ıt is connecting with a heat pump.( ı will use ıt for counter flow)
I know this formula from heat transfer lecture but for my situation I dont know what is the value of Q and Area to calculate U ( overall heat transfer coefficient)
q = UA (dTlm)
I m pumping to heat exchanger 1590 kg/hr water at 4 Degree of temperature. So for this what will be the my overall heat transfer coefficient in type 5b
thanks
