Hydrodynamics of Packed Bed the set up is capable to study the loading and flooding characteristics. It is a packed column packed with Raschig Rings where the Air is counter currently fed to column. Liquid holdup in the column increases the weight of column and also reduces the effective porosity of packing. This reduction in porosity decreases the gas velocity, increases the pressure drop and changes the value of mass transfer co-efficient. The water is fed from the top of the column and loading & flooding characteristic are observed on various flow rates of Air and Water.

Measurement of Magnetoresistance of Semiconductors
It is noticed that the resistance of the sample changes when the magnetic field is turned on. The phenomenon, called magnetoresistance, is due to the fact that the drift velocity of all carriers is not same. With the magnetic field on; the Hall voltage V=E t=|vx y H| compensates exactly the Lorentz force for carriers with the average velocity; slower carriers will be over compensated and faster one under compensated, resulting in trajectories that are not along the applied field. This results in an effective decrease of the mean free path and hence an increase in resistivity. Here the above referred symbols are defines as: v = drift velocity; E = applied electric field; t = thickness of the crystal; H = Magnetic field.
Experimentental Set-up for Magnetoresistance
The set-up consists of the following:
1. Four probe arrangement
2. Sample: (Ge: p-type)
3. Magnetoresistance set-up, DMR-01
4. Electromagnet, EMU-50V
5. Constant Current Power Supply, DPS-50
6. Digital Gaussmeter, DGM-102
(1) Four Probe arrangement°
It consists of 4 collinear, equally spaced (2mm) and individually spring loaded probes mounted on a PCB strip. Two outer probes forsupplying the constant current to the sample and two inner probesfor measuring the voltage developed across these probes This eliminates the error due to contact resistance which is particularlyserious in semiconductors. A platform is also provided for placing thesample and mounting the Four Probes on It.
(2) Sample
Ge Crystal (n-type) dimensions: 10 x 10 x 0.5mm.
(3) Magnetoresistance Set-up, Model VT-01
This unit consists of a digital millivoltmeter and constant current power supply The voltage and probe current can be read on the same digital panel meter through a selector switch.
(a) Digital Millivoltmeter
lntersil 3½ digit single chip ICL 7107 have been used. Since the use of internal reference causes the degradation in performance due to internal heating an external reference have been used. Digital voltmeter is much more convenient to use, because the input voltage of either polarity can be measured.
Specifications:
(b) Constant Current Power Supply
This power supply, specially designed for Hall Probe, provides 100% protection against crystal burn-out due to excessive current. The supply is a highly regulated and practically ripple free dc source.

Test method :- Aniline point is used to characterize pure hydrocarbons and to indicate the aromatic content of hydrocarbon mixtures. Equal volumes of aniline and sample or sample plus n-heptane are stirred together while being heated at a controlled rate. After the two phases become miscible, the mixture is cooled at a controlled rate and the temperature at which the two phases separate is the aniline point or mixed aniline point of the sample.
Standard :- Conforms to: astm d611; ip 2; iso 2977; din 51775; ftm 791-3601. for aniline point and mixed aniline point determinations according to method b. Stirs aniline-sample mixture in a borosilcate glass thin film tube suspended in a heating bath. Thin film of mixture flows over a light well illuminated by a variable 6v lamp. Adjust heating rate per specifications using accessory powertrol heater. When lamp filament brightens inside well, allow mixture to cool until the two phases separate as indicated by obscuring of the lamp filament. Consists of thin film tube; 400ml pyrex™ beaker; cover assembly with bath stirrer, sample pump rotor and cooling coil; 6v lamp with line cord; and drive motor. Positive drive pulley system rotates sample and bath stirrers. Accessory powertrol heater has variable stepless control and a reference dial for repeatable control of heating rate.
