Oscillating Flow and Pressure Drop in Horizontal Pipes

Abstract

The study’s main aim is to evaluate oscillating flow and pressure drop in horizontal pipes. First, the equipment is calibrated to ensure the correct flow rate. Calibra- tion is done with three methods. These are, Calibration under a constant flow rate, Calibration under continuous pressure (height), and calibration under variable pressure and flow rate. Proceeding from calibration, water is treated with two polyanionic cellulose polymer concentrations. The concentrations are 1% and 2% PAC, respectively, 5g PAC and 10g PAC added to 5l water. Test performed are Oscillatory tests using PASCO, Amplitude sweep, Fast Fourier transform, and hysteresis test.
