Water Cooling Tower Apparatus
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.
SPECIFICATION:
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.
Measuring tank to measure outlet water flow.

Thin Cylinder Apparatus
A heavy bench top unit for studying the stress and strain in a thin walled cylinder under internal pressure. A thin walled cylinder is mounted between two support blocks. Internal pistons and seals create oil sealing. A handwheel at one end of the apparatus enables the cylinder end conditions to be adjusted to either open or closed. The internal pressure is adjusted by means of a hydraulic hand pump on the apparatus. An analogue pressure gauge displays the internal pressure whilst a pressure transducer gives feedback to the Data Acquisition Interface and Software supplied. Strain gauges are arranged on the external surface of the cylinder to measure the radial and circumferential surface strain. The strain gauges are at various angles.
