SEPARATING & THROTTLING CALORIMETER
SEPARATING CALORIMETER : - It consists of two concentric chambers, the inner chamber and the outer chamber, which communicates with each other through an opening at the top. As the steam discharges through the metal basket, which has a large number of holes, the water particles due to their heavier momentum get separated from the steam and collect in the chamber. The comparatively dry steam in the inner chamber moves up and then down aging through the annular space between the two chambers and enters the Throttling Calorimeter. THROTTLING CALORIMETER : - It consists a narrow throat (Orifice). Pressure and temperature are measured by pressure gauge and thermometer. The steam after throttling process passes through the heat exchanger and condensate is collected. Steam Generator is also provided to supply the saturated steam (Max.) at 2kg/cm2 pressure.
TWO PHASE HEAT TRANSFER APPARATUS-
Boiling and condensation processes in the transfer of heat from a hot to a colder region in numerous applications, e.g. power generation, refrigeration, refining, heat transmission, etc.
FINNED TUBE HEAT EXCHANGER APPARATUS-
Finned tube Heat exchanger is a device in which heat is transferred from one fluid to another. The apparatus consists of a concentric tube heat exchanger. Hot water flows through inner tube in one direction only and cold water flows through the outer tubes. Direction of cold fluid flow can be changed from parallel or counter to hot water so that unit can be operated as parallel or counter flow heat exchanger. Flow rates of hot and cold water are measured using Rota meters. A mono block pump is used to circulate the hot water from a re‑cycled type water tank, which is fitted with heaters and Digital Temperature Controller.
UNSTEADY STATE HEAT TRANSFER APPARATUS-
To determine the internal thermal resistance of the body by calculating Biot number for solid Cylinder.
THERMAL CONDUCTIVITY OF LIQUID MEASURING
The apparatus is designed to determine thermal conductivity of different liquids. The apparatus consists of a heater. The heater heats a thin layer of liquid. A cooling plate removes heat through liquid layer, ensuring unidirectional heat flow. Temperature is measured across the liquid layer and complete assembly is properly insulated. A proper arrangement for changing the liquids is provided. The whole assembly is kept in a chamber.
