In a circulating pipeline, the water pump keeps running; how can the temperature increase of the water in the system be estimated?
Thread Content
The system uses a small experimental unit operating at a pressure of 5 MPa; the pump is a plunger pump with a flow rate of 10 L/min. The liquid is pumped in a cyclic manner to the filtration unit. Since the filtration elements are sensitive to temperature, a jacket has been considered for the feed tank located ahead (which is open-ended), with an estimated area of 0.1 m2 – however, there is concern that this may not be sufficient. Piping DN15/DN25. I wonder how this temperature rise is generally considered and estimated? Thus, it is necessary to calculate whether an additional heat exchange device is required Thank you~
Heat generated by pipeline friction losses
Yes, the key question is whether there is an algorithm for this
It is recommended to use built-in coils for heating/cooling inside the raw material tank; having more coils allows the temperature within the tank to be controlled by adjusting the flow rate or temperature of the heat/cold source
10 L/min, which is 0.6 m3 per hour; with such a low flow rate, excessive cooling is sufficient. If you’re still concerned, you can simply use the principle of energy conservation to estimate it: subtract the kinetic energy associated with the flow rate of the medium from the rated power of the pump; the resulting difference represents the power that needs to be dissipated as heat.
