Drag Coefficients Apparatus | FluidoSurge-X 180
The Drag Coefficients Apparatus is designed for experimental study of particle motion in fluids. It enables determination of drag coefficients for falling particles over a wide range of Reynolds numbers. Made by Scientico India, ISO 9001:2015 certified, and supplied with a calibration certificate and operation manual.
The Drag Coefficients Apparatus FluidoSurge-X 180 is designed for experimental study of particle motion in fluids. It enables determination of drag coefficients for falling particles over a wide range of Reynolds numbers. The apparatus supports comparative studies using fluids of different viscosities and particles of varying size and material. It is suitable for fluid mechanics laboratory teaching and experimental analysis.
Product Overview
The SCIENTICO Drag Coefficients Apparatus FluidoSurge-X 180 consists of two vertically mounted transparent tubes filled with fluids of different viscosities. Spherical particles are released into the fluid and allowed to fall under gravity, reaching a steady terminal velocity. By measuring the time taken for particles to travel a known distance, students can calculate sinking velocity and determine drag coefficients. The apparatus allows correlation between drag coefficient and Reynolds number, supporting analysis of particle fluid interactions and boundary layer behavior.
