I have a tank of oil at 55 degrees c. I plan to run a copper pipe 8mm in diameter (1mm thickness) into a coil 15m long inside the tank. For all purposes of assumption, the copper pipe is perfectly transferring heat across to the oil and vice-versa.
I have a pump of 10l/min that circulates this oil around the tank, so we will just assume that the 55degree oil is always well distributed.
I want to cool this down as much as possible, and was wondering if I was running tap water (28degrees), cold water (10degrees), how much would the coil be able to bring the temperature down by. We will assume that water is running through the coil at 5l/min.
Specifically I'm looking to convert the heat removal capacity into temperature in degrees. So that I can decide whether I want to
i) Use cold or room temperature water ii) Whether this concept works at all
