Hi guys,
I am running a heat transfer experiment along with my PhD that involves a closed pipe-in-pipe system. My coolant (jacket) fluid is flowing from a tank by a centrifugal pump through the jacket and it comes back to the tank while my hot fluid goes through a same process.
In my inner pipe, hot fluid is oil and the test takes several hours so the heat can be transferred then I can measure it. Obviously, since I have a closed system, both hot fluid and coolant fluid are going to get cooler and hotter respectively by time. However, the increase in coolant's fluid temperature is partially due to pump. Therefore, I need to know how much heat is generated by pump so I can rule it out from my main heat transfer calculation.
Can anyone help me with a methodology that is able to give the produced heat by pump without knowing its efficiency? please also be aware that, I know the temperature increase versus time for different coolant fluid volumes with no hot fluid inside the inner pipe (which means the temperature increase is only due to pump).
The attached picture is the graph of temperature increase versus time for different coolant fluid volumes.
Thank you so much
