Critical Speed Investigation Apparatus

Product Code: LBNY-0005-10100076 - (Critical Speed Investigation Apparatus)

The rotor is held on the base frame with pivoting bearings. The weights and bearings can be placed at any location along the shaft and attached securely with quick-acting clamps. This benchtop unit is used to show the resonance and critical bending speed on rotating shafts. The construction of the rotor of a thin, flexible shaft and rigid weights facilitates the theoretical comprehension. It is possible to switch speeds during the experiment as desired. A transparent protective hood covers the rotating parts. A set of electrical vibration sensors with clamping set is also available. It is driven by a flexible coupling. Two motor speeds can be fine-adjusted and preset with ten-speed potentiometers. They are controlled electronically and displayed digitally.

Demonstration Cooling Tower

Product Code: LBNY-0005-11200076 - (Demonstration Cooling Tower)

A fan with a flow control valve is connected to the bottom tank, and air is driven upwards through the column and exhausted at the top. Instrument are provided for measurement air flow rate, water flow rate, pressure drop across the cooling tower, temperature and moisture of the inlet and outlet air. This is a Cooling Tower Demonstration Unit. Water is heated in the storage tank, pumped through a flow meter and sprayed at the top of the tower. The water is cooled mainly by evaporation and drops to the bottom tank. Makeup water is admitted to the storage tank through a float valve. The packing in the tower breaks the water into thin films and droplets. 

Experiments:
Application of steady flow equation to energy balance.
Cooling tower performance at various air and water flow rates with different inlet water temperatures.
Observation of water flow patterns and distribution.
Measurement of water and air flow rates, temperatures and humidity.
