Mild Steel Round Lagged Pipe Apparatus, For Chemical Laboratory

The unit consists of a three concentric pipes of a very small thickness as compared to diameter. They are arranged concentrically over two supports and closed with the help of two disces. The annual in between the cylinders are filled completely by two different insulating materials. Thermocouples at proper position are used to measure the temperature. Inside the inner pipe a nicrome wire heater is placed. Heat input to the heater is given through a variac and measured by a voltmeter and ammeter. By varying the heat input rates wide range of experiments can be performed.
Specification:
- G.i pipe inside-5 cm dia. Approx.
- G.I. pipe middle-10 cm dia Approx.
* G.I pipe outer-15 cm dia Approx.
* Length of pipes-1 meter Approx.
Features:
* The concept of double and single lagging can be studied easily.
* Effects of different insulating material combinations can be seen.
* Easy to operate.
* Ideal for group studies and demonstration.
Range Of Experiments:
* To determine heat flow rate through the lagged pipe and compare it with the heater input for known values of thermal conductivity of lagging material.
* To determine the thermal conductivity of lagging material by assuming heater input to be the heat flow rate through the lagged pipe.
* To plot the temperature distribution across the lagging material.
Service required:
* Suitable bench area to mount the instrument.
* 230 V A.C. supply with earthing connection.
