Q-1
Calculate the minimum velocity at which spherical particles of density 1600 kg/m and of
diameter 1.5 mm will be fluidised by water in a tube of diameter 10 mm on the assumption
that the Carman-Kozeny equation is applicable. Discuss the uncertainties in this calcula-
tion. Repeat the calculation using the Ergun equation and explain the differences in the
results obtained.
Q.4 (b) In a scintillation detector, the 662 KeV
photo peak of Cs137 source is observed at 6.0 V and
the: full width at the half maximum of the photo peak
is 0.72 V. Find the percentage resolution of the
scintillator detector. Also find its resolution in KeV.
Some experiments require calibration of the equipment before the mea-
surements can be made. Any random errors in the calibration will usually become
Systematic errors in the experiment itself. To illustrate this effect, consider an exper-
iment on the Zeeman effect, in which a magnetic field causes a tiny shift in the

frequency of light given out by an atom. This shift can be measured using a Fabry-
Perot interferometer, which consists of two parallel reflecting surfaces a distance d
apart (where d is typically a couple of millimeters). To use the interferometer, one
must know the distance d; that is, one must calibrate the instrument by measuring
d. A convenient way to make this measurement is to send light of an accurately
known wavelength A through the interferometer, which produces a series of interfer-
reference marks
