The apparatus consists of a forced draught, counter flow type-cooling tower. A blower supplies cooling air. Air enters the tower at the bottom. Hot water is, obtained from a geyser. Hot water is sprayed over the mesh packing through the nozzles and it flows downwards. Evaporative cooling of water occurs due to the current of air and water gets cooled. This student can study the operation of cooling tower and calculate the energy balance.
Cooling tower, fabricated of M.S. Sheets, 200 X 200 mm. cross section,
1.2m. height with Perspex front. Wire mesh packing is provided in the tower.
Geyser – 3 Kw Capacity to provided hot water.
Centrifugal blower, 1 HP capacity to force air through the tower.
Multichannel Digital Temperature indicator to measure temperature at various points.
Rotameter to measure inlet water flow.
