STUDI EKSPERIMENTAL PENGARUH VARIASI KECEPATAN SUPERFISIAL AIR-UDARA TERHADAP PRESSURE DROP PADA PIPA PLEXIGLASS BERORIENTASI VERTIKAL DENGAN ARAH ALIRAN SEARAH

This study aims to analyze the effect of variations in air-water mixture superficial velocity (Jmix) on pressure drop in vertical co-current two-phase flow and compare the experimental results with the theoretical calculations. The experiment was conducted using a 1-inch diameter plexiglass pipe with a test section length of 1 meter. The working fluids used were water and air, with water flow rates varying from 0,00028 m3/s - 0,00047 m3/s and air flow rates from 0,00020 m3/s - 0,00040 m3/s. Pressure data acquisition was performed using a U-tube manometer at two tapping points. The experimental results were then compared with theoretical calculations comprising static, momentum, and frictional pressure components. The results indicate that an increase in the mixture superficial velocity Jmix leads to a decrease in pressure drop. This phenomenon occurs because the increasing gas fraction in the flow reduces the total fluid density, thereby significantly reducing the hydrostatic pressure component, which is the largest contributor to pressure drop in vertical pipes. Experimental pressure drop values were found to be lower than theoretical values, with a maximum experimental value of 4778.05 N/m² at Jmix 0.9546 m/s and a minimum of 398.17 N/m² at Jmix 1.7225 m/s. These discrepancies are attributed to flow fluctuation and instability of slug flow patterns.
