Question: the uconn foundry wants to begin producing copper powder for...

Question details

The UConn Foundry wants to begin producing copper powder for a new research grant. The research team wants to determine what size particles to produce in order to form 5 cubic meters of powder the fastest. Liquid copper particles are dropped at 1300 °C into a water bath at 25 °C. The bath has a refrigeration system that can only remove a maximum of 500 W/min. What size particles (solid) should be used and at what volumetric rate should the particles be fed to the bath such that the temperature of the bath does not change from 25 °C? Show all relevant plots and data to prove which powder size is the fastest and the respective feed rate Hint: Take into account the change in density of copper Data for Cu Density Solid Liquid8490 k m3 Freezing Point Specific Heat 8970 kg m3 377J kg-K-1 5021 kg-iK-1 Thermal Conductivity 346 Wm-1K-1 311 Wm-1K-1 Data for Water Quench 1358K Heat of Fusion 2.07x105Jkg-1 Temp Range 1450-920K 920-360K Heat Transfer Coefficient 450 WmK-1 2270 W m-2K-1
