DESCRIPTION :-

It is designed to study Coriollis Component of Acceleration of a slider crank mechanism. Here the mechanical slider system is replaced by a continuous stream of water flowing through a steadily rotating pair of tubes. These tubes can be rotated at various speeds by using a swinging field motor which also acts as dynamometer. A Perspex window on top of the tank gives clear view of the process and prevents splashing of the water over the side of the tank. The dynamometer continuously measures torque applied to the rotating tubes.
The Equipment is self contained, water recirculating, provided with its own speed control unit and separate water circulation pump.

SPECIFICATIONS :-

1)Main Tank : Fabricated out of fibber glass plastic sheet.
2) Rotating Arms : 9mm/6mm orifice dia, 300 mm long.
3) Rotameter : 300 to 3000 LPH
4) Electric Motor : D.C. Swinging field, 0.5 H.P. 50 RPM
5) Mono block Pump : Single phase, pump with Motor 2400 LPH discharge.
6) Control: Consisting of ?
(a) pump switch
(b) Variac Speed Control
(c) Speed Indicator
(d) Main Switch.
7) Rigid Support Structures .

RANGE OF EXPERIMENTATION :-

Coriollis Component of Acceleration can be detrmined at various speeds of rotation and water flow rates.

SERVICE REQUIRED

1) Single phase A.C. Electric Supply 230 V A.C. 50 Hz.
2) Floor Space : 1.5 m x 1.5 m.

DESCRIPTION :

The total set up comprises of Centrifugal fan which blows air through a square duct which consists of several sections as following.
(A) INITIAL CONDITIONING SECTION
This section comprises of a cooling coil circuit, heater section and steam humidification system. This section enables simulation of normal year round weather conditions to some extent in the confined space of the duct.
B) FIRST OBSERVATION SECTION
This section consists of flow stabilization zone and temperature measurement section. Here condition of simulated air coming out of the first conditioning section is observed and recorded.
C) SECOND CONDITIONING SECTION
This section incorporates cooling coil, heaters and humidifier tubes as in first conditioning section. The equipment incorporated in this section can be operated suitably to bring final air condition somewhere near comfort conditioning zone.
D) SECOND OBSERVATION SECTION
This section incorporates flow stabilization zone and measurement section where final condition of air is observed and recorded after conditioning the same in second conditioning section.
