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 and orifice meters.

Day 2 of the experiment was performed on April 23, 2013. More testing was done on both apparatus’ in order to obtain enough data for error propagation.

Sincerely,

William Kwendi

Abstract - William Kwendi
This experiment is broken up into two experiments: Fluid Flow Meters and Distillation Tray Hydraulics. The purpose of Fluid Flow Meters was to determine the operating characteristics of Venturi and orifice meters. According to Bernoullli’s equation, the slope of a log-log plot of flow rate vs pressure drop was expected to be 0.5. After much experimentation of different flow rates and the pressure drop that came with these flow rates, the Venturi meter had a slope of 0.53 ± .03, and orifice meter data had a slope of 0.46 ± .02. The data showed as the water flow rate was increased, the pressure drop also increased, which is in accordance with Bernoulli’s equation. The discharge coefficient is a ratio of the efficiency of the actual discharge of the fluid over the theoretical discharge. The average calculated coefficient of discharge for the Venturi meter was 0.984 ± 0.001 and for the orifice meter has an average calculated coefficient of discharge of 0.540 ± 0.001. The discharge coefficient should theoretically be 0.98 for the Venturi meter, and 0.62 for the orifice meter. The percent error of the discharge coefficient was 0.046% and 9.2% for the Venturi and orifice meters, respectively.

The purpose of the second experiment, the Tray Hydraulics, was to examine the vapor and liquid tray hydraulics parameters for sieve type crossflow distillation trays. Water flow rates were varied in intervals of 15 in. H2O, ranging from 0 to 75 in. of H2O. For each water flow rate, 5 air flow rates were measured from 0.01 to 0.95 cm3/s. The pressure drop increased as the water flow rate increased if the air flow rate was held constant, and when the air flow rate was increased with the water flow rate being held constant. The data showed that the percent flooding was a maximum at...
