It represents the theoretical and physical aspects of the fluid in motion‚ as it flows naturally or when effected by a force. This application can be applied to liquids and gases providing a deeper understanding of pure sciences such as atmospheric‚ geophysics and

OK 73019 Dr. Nollert‚ The experiment performed was Experiment IV: Fluid Flow Meters and Tray Hydraullics. The group was composed of Alex Long‚ Khanh Ho‚ Tricia Heitmann and myself. The first day of experimentation was April 16‚ 2013. On this day‚ Alex and I ran the sieve tray apparatus to study the vapor and liquid tray hydraulics parameters for sieve type crossflow distillation trays. Tricia and Khanh ran the fluid flow apparatus to determine the operating characteristics of the Venturi
