Determine the magnitude and direction of the anchoring force needed to hold
the horizontal elbow and nozzle combination in place as shown in the Figure
Q3 (a) below. Atmospheric pressure is 100 kPa(abs). The gage pressure at
section (1) is 100 kPa. At section (2), the water exits to the atmosphere.

Applying Dimensional Analysis to the human anatomy studies, it was found
that the velocity, c, at which pressure pulses travel through arteries is a function
of the artery diameter, D, and wall thickness, h, the density of blood, p, and the
modulus of elasticity, E, of the arterial wall.

Perform a dimensional analysis for this study showing all the steps using
the density of blood, p, artery diameter, D, and the modulus of elasticity,
E, as the repeating variables in either FLT system or MLT system.
(ii)
Atherosclerosis is the thickening of the arteries caused by a build-up of
plaque in the inner lining of an artery. With the aid of dimensional
analysis, determine how the velocity will change if the wall thickness is
doubled while keeping all other parameters constant.
