Fluid Mechanics - True or False
1) Reynolds number represents the ratio of viscous force to the
inertia force.
2) The entrance length (Le) for turbulent flow is greater than that
for laminar flow for the same pipe diameter.
3) Increase the fluid viscosity leads to decrease the
turbulence.
4) For laminar steady flow between parallel fixed plates, the
pressure drop increase with increasing the thickness of the fluid
layer between them.
5) For laminar steady flow for pipe, the...

5. By statute, the government is not permitted to take
cost-effectiveness criteria into account when deciding to cover new
technologies under Medicare. 6. The purpose of a Diagnosis Related
Group (DRG) is to prioritize patients who need care most urgently.
7. Suppose a politician suggests means testing the Medicare
program. This will have no adverse effects on working or savings
decisions.

An incompressible liquid flows through a straight horizontal
pipe. Friction of the fluid within the pipe causes a small amount
of heat to be transferred from the fluid; to compensate, flow work
must be done on the fluid to move it through the system (so
W(dot)fl is greater than zero.
a) How are V(dot)in and V(dot)out related, where V(dot) is the
volumetric flow rate of the liquid? (Remember, fluid is
incompressible)
b) How must the pressures of Pin and Pout...

State whether the followings are True or False? (1) The angle of
internal friction can vary from 0 to 90˚ since it is an angle. (2)
A degree of saturation of 40% implies that 40% of the total volume
consists of water. (3) Clays can have both cohesion and angle of
internal friction. (4) In the triaxial test the horizontal plane is
the major principal plane. (5) Piping (failure due high exit
hydraulic gradient downstream) starts upstream and then progress...

Historically, the structure of retailing in India was very
fragmented with a large number of very small stores serving most of
the market. Supply chains were also very poorly developed and
fragmented. As recently as 2010, larger format big box stores,
chain stores, and supermarkets only accounted for 4 percent of
retail sales in the country (compared to 85 percent in the United
States). This might sound like an ideal opportunity for efficient
foreign retailers such as Walmart, IKEA, Tesco,...
