HEAT TRANSFER THROUGH LAGGED PIPE APPARATUS

Product Description

Micro Teknik The setup isdesigned and fabricated to study lagging phenomenon in case of pipes. Itconsists of three concentric pipes of small thickness as compared to diameterand are arranged concentrically, and closed with the help of two discs.

Two different insulatingmaterials fill the annuli between the cylinders compactly.

Temperature Sensors are fitted tomeasure the temperature of pipe walls for radial outward heat flow measurement.Inside the inner pipe, a Nichrome wire heater is placed axially. Heat input tothe heater is given through a variac and measured by Digital Voltmeter andDigital Ammeter.

By varying the heat-input rates,wide range of experiments can be performed

Experiments

To estimate the actual rate ofheat transfer through the composite cylinders from the measured interfacetemperature of the known value of thermal conductivity of the two insulatingmaterials.

To determine the effectivethermal conductivity of the composite cylinders

To determine the theoreticaltemperature profile within the composite cylinders Utilities Required
