Heat Transfer Lagged Pipe

FEATURES:

1. Study of the connected of double & single lagging 
2. Study of effects of different insulating material combinations
3. Electrical input control & measurement with complete penalized instruments.
4. Digital Temperature indicator.

INTRODUCITON:
Lagging of pipes is required to prevent leakages of heat. The Apparatus is designed to study the lagging phenomenon. In Lagged Pipe Apparatus three concentric pipes are arranged between the pipes are filled compactly by two different insulating materials and heater is provided at the center of inner pipe. Temperature at various points is measured with Temperature indicator. Heat input is measured by Voltmeter - Ammeter. The assembly is mounted o angle frame.

SPECIFICATION: 
1)  Pipes
i)    M.S. Pipe inside - 5cm dia. Approx   
ii)   M.S. Pipe Middle - 10 cm dia approx.
iii)  M.S. Pipe Outer - 15cm

2) Length of Pipes -1m approx.
Control Panel consisting of 
a)  Voltmeter - 0 - 100/200 volts.
b)  Ammeter - 0 - 2 Amp.
c)  Diammerstat for heater, 0-230 V, 2 Amps.
d)  Digital Temperature indicator, 0-300 ⁰ C with 10 C least count, using chromel-almel  thermocouples, provided with cold junction compensation.
4)   Nichrome cartridge heater of suitable capacity  and length

EXPERIMENTATION: 
1)   To determine heat flow rate through lagged pipe and compare it with the heater input for known values of

thermal conductivity of lagging material.
2)   To determine thermal conductivity of lagging material by assuming input to be heat flow rate 
3) To plot temperature distribution across lagging material.
