  • Experiment #10: Pumps – Applied Fluid Mechanics

    Heat pumps are mechanical devices that extract low-grade heat from one source and transfer the heat to another. The advantage of a heat pump is that it up-grades the heat and delivers it at a higher temperature than the source from which the heat was extracted. Heat pumps are usually based on refrigeration cycles.
