This media file showcases a laboratory apparatus designed for studying the hydrodynamics of a packed bed and liquid hold-up, likely in an academic or industrial setting in Jaipur, India. The core of the setup is a bright red, vertically oriented main panel that displays various measurement and control instruments. On its upper left, a white control panel features switches labeled "MAIN," "WATER PUMP," "AIR VALVE," and "WATER VALVE," along with indicator lights, suggesting electrical and fluid flow control. The red panel itself houses two vertical rotameters used for measuring fluid flow rates, a circular pressure gauge, and two U-tube manometers, each equipped with a ruler, which measure pressure differences across sections of the packed bed. Yellow knobs, partially labeled "INCREASE," are present for adjusting operational parameters. Branding on the panel includes "D. P. P. INSTRUMENTS," an ISO certification logo, and the Indian national emblem with "सत्यमेव जयते" (Satyameva Jayate), affirming the Indian context. Attached horizontally at the bottom of the main panel is a clear cylindrical column, the "packed bed," filled with numerous small, light-colored, granular particles. This column is connected to the manometers via clear flexible tubing to monitor pressure at different points. The apparatus incorporates a network of white and grey PVC pipes, valves, and clear flexible hoses for fluid circulation. To the right, a white collection tray or sink with a grate is visible, suggesting a drainage system for the circulated liquids. The background shows reflections of overhead lighting and other laboratory equipment on a tiled floor, indicating an indoor lab environment. No people are present in the image.
