Students are trained in basic Unit Operations (Network of tubes, pumps, heat exchangers)
Students learn to work with computing methodology and a commercial software to design unit operation processes s learn design unit operation processes
Students learn to design heat exchangers and calculate friction losses in network of tubes
Students learn to work and co-operate in multidisciplinary teams to present their results in original reports
To attend the module the student is encouraged to refresh basic Fluid Mecanics and Heat Transfer conecpts.
