Using HYSYS to simulate heat exchangers for calculating heat transfer area?
Thread Content
After specifying the pressure, temperature, flow rate of the cold material and its outlet temperature, as well as the temperature, pressure, flow rate of the hot material’s inlet and its outlet temperature, why is there a warning displayed below: Warning:E-100-Over Specified? What does this mean? Can the results of that calculation be used? Thanks for the advice
There are too many regulations; just remove one of the temperatures.
Reply to 2# scbnmao: I removed the outlet temperature of the hot stream, but why is this warning still appearing? Please give some advice! Thank you!
Is there also a specified pressure drop for the heat exchanger? If the pressures in your import and export logistics are fixed, eliminate the pressure drop within the heat exchanger
Reply to 4# scbnmao: Nothing is specified regarding the contents inside the heat exchanger, and the pressure value wasn’t entered either – yet there’s still an error! I’m confused. Could you please give me your email address or QQ number? I’ll send it to you; I can’t transmit it here
You can take a look at the degrees of freedom; you’ve provided too many known conditions
