Question: Please help me (I’m an outsider). Thank you! ! !

The incoming medium is water; the inlet temperature is 20 degrees, and the flow rate is 360 liters per hour. The inner diameter of the iron pipe is 30 mm. The desired outlet temperature is 120 degrees. What is the required heat exchange area? I want to calculate how much power is needed to achieve an outlet temperature of 120 degrees. I have no experience in this area – what formulas are needed, and which books can help me solve this problem? Please advise, thank you! ! ! ）
The book \"Heat Transfer\" meets your most basic needs for heat transfer calculations
1. Calculating power is middle school knowledge. 2. It takes you a few months to learn how to calculate area.
Thank you. I just bought a book on \"Heat Exchanger Process Design\" – is it the right choice? I’ve never dealt with this kind of knowledge before and didn’t know where to start; one really regrets not having such a book when it’s needed!
Thank you! I’ll read the book first and ask for help if I don’t understand :)
To understand the basic concepts, please refer to the following formulas: Q = U * A * (LMTD) = M * CP * ΔT. Here, Q represents heat, U is the thermal conductivity, A is the area, LMTD is the logarithmic mean temperature, M is the mass, CP is the specific heat, and ΔT is the temperature difference. With these formulas, it’s possible to calculate the basic area. Of course, it’s not that simple in actual design work; but having these concepts helps you to conduct basic verifications when preparing purchase requests or using data provided by manufacturers
Thank you all! The issue has been resolved, thank you!
