Unit Conversion

Standard units are also called SI units. SI units are used for measuring a physical quantity satisfying certain conditions. There are two types of units: fundamental units and derived units. Fundamental units are physical quantities that are independent, that is, they do not depend on other quantities like mass, length, or time. There are plenty of quantities in our lives which need to be measured and compared. Measuring is the comparison of a particular physical quantity with its reference value. A unit is a measure of a fixed physical quantity. A physical quantity is the product of a unit and the numerical value we need to compare with.

Question

A test setup is shown. A cylindrical mold
of 4 inches in diameter is filled to a
height H1 = 0.2 ft., with silt whose
coefficient of permeability K1 = 3.8 x 10
3 ft/min.
A second coaxial mold is placed on the
top of the first mold whose inside
diameter is d = 1.5 inches and whose
%3D
height is 0.30 ft. Its Thickness is
negligible. The inside of this second
mold is filled with the same silt, but the
annular ring outside the small tube and
the outer tube is filled with sand whose
coefficient of permeability is K2 = 7.5 x
104 ft/min. The test set up is a
permeability of constant head. Water is
placed in the mold and maintained at a
level h = 1.5 ft. above the level of the
outlet. It maybe considered that
altogether, the system consists of a
fictitious soil of thickness H= H1 + H2 =
0.5 and the coefficient of permeability
Kr.
