SHELL AND TUBE HEAT EXCHANGER (water to water type)
To determine heat transfer rate, heat transfer coefficient, LMTD. The unit consist a two design ,mild steel shell houses the copper pipes.
End box for shell which carriers a baffle at the center to make the heat
exchanger of two pass type. cold fluid passes out side the tubes
in the shell. Hot water flows inside the tubes. Temp. of hot water & cold fluid measured by thermometer.flow rates and temp. of hot and
cold fluid can measured.

SHELL AND TUBE HEAT EXCHANGER ( air to water type )
To determine Heat transfer rate, heat transfer coefficient, LMTD &
effectiveness of heat exchanger in laminar as well as turbulent
flow of air. A m..s. shell,in which copper tubes are fitted, baffle
in the end box make the tube arrangement two pass type.
Cold fluid is air enters the shell and flows over the tube.
Hot fluid is water obtained from geyser & flows through the tubes.
25% cut buffles are provided in the path of air. Measuring tank for
water flow rate, Orifice with water manometer for air flow,
thermometer for inlet and out let temperature

HEAT EXCHANGER SECTION
PLATE TYPE HEAT EXCHANGER
To determine heat transfer rate, LMTD, heat transfer coefficients and
effectiveness of heat exchanger.The unit consists cold and hot fluid
obtained from geyser. Inlet and outlet connections are positioned to
make the Exchanger counter flow type. Hot and cold fluid pass
between alternate plates.

REGENERATIVE HEAT EXCHANGER APPARATUS
The unit consists of two columns filled with steel balls. Two blowers
are provided for hot and cold air. The columns are filled with steel balls
One column is getting heated by hot air while other by cold air.
Thus alternately columns are heated and cooled and operation is continuous. |

THERMAL CONDUCTIVITY SECTION
THERMAL CONDUCTIVITY OF METAL ROD
Determines thermal conductivity of metal rod. a copper bar, heated at
one end, heat sink at other end, teat section of bar is properly insulated
& thermocouples are attached for temperature. Heat conducted through
the section of bar is measured by heat collection in water cooled heat
sink.A panel compresing of controls and measurement is provided. |

THERMAL CONDUCTIVITY OF INSULATING POWDER
Determines thermal conductivity of insulating powder by sphere in
sphere method. A copper sphere in which a mica heater is fitted.
the sphere is surrounded by another bigger sphere and between the
two sphere,the test insulating powder is filled. Heat of the heater
radically flows outwards in all directions through powder. temp.
Across the powder are measured. by knowing input to the heater
conductivity of powder can be dtermined.

THERMAL CONDUCTIVITY OF LIQUID
An electrical heater sandwitched between aluminum plates. heat loss
from hot plate is prevented by using two guard heaters and heat of hot
plate is made to flow through specimen. cold plate on opposite face of
liquid removes heat from liquid by circulation of water. Input to heaters
can varied & measured. Digital temp Indicator to measure temperature. |

THERMAL CONDUCTIVITY OF INSULATING SLABS
BY 10260 GUARDED HOT PLATE METHOD
To determine thermal conductivity of specimen,main heater and radial
heater sandwitched between copper plates. Specimen in the form of
slabs of equal thickness are placed on either sides of heaters and
cooling plates. other side of specimen water is circulated. Radial guard heaters ensures all heat of main heater passes axially through
the specimen, collected by cooling plates. By knowing the themp.
And heat input, thermal conductivity of specimen can be calculated.
