Heat Exchanger Metric Formulas

AI Thread Summary
To calculate the length of copper pipe needed to heat water in a "kolam" to 45 degrees Celsius using a heat pump at 55 degrees Celsius with a flow rate of 1 cubic meter per hour, specific formulas for heat transfer and pipe length are required. The discussion highlights the need for simple formulas to facilitate this calculation. A link to a relevant article on helical coil heat exchangers is provided as a potential resource. Participants are encouraged to share any straightforward methods or formulas they may know. Accurate calculations are essential for effective heat exchange in this application.

Hello,

I need help to calculate the length of pipe in copper (d=22mm) to get the water in "kolam" to be 45 degree celcius and the heat pump temp is 55 degree celcius, heat pump water flow is about 1 meter cubic per hours, any simple formulas ?

thank you for help
