We have to transport 250000 std m3/day of CO2 (@ atmospheric pressure and 50 °C) fron one site to other, 90 km apart. There are two option: 1) compress de gas and send it in a pipeline, 2)condense the CO2 and send it as liquid in a smaller pipeline or by truck; and vaporize at the other end...
The similarity rules for centrifugal pumps dictate that homologous operating points of a certain pumps (changing velocity) have same efficiency. Starting at BEP of a pump runing, say, 1750 rpm (max. efficiency = 80%), the similarity rules predict that there must be an homologous operating point...
I am working in natural convection on a vertical plate. The problem is how to calculate the heat transfer coefficient. Invariably text books give correlations bassed on Nusselt, Grashof, and Prandtl numbers for a hot plate in a cold fluid (gas or liquid). What happened with a cold plate in a hot...
