Example:\
\\\ ho =850k(g)/(m^(3))
\ An incompressible viscous fluid flows between two horizontal parallel plates as shown. The plates are spaced
0.5cm
apart and are very wide perpendicular to page. Flow is laminar and velocity profile at any cross section is given by,\
u=-(Y^(2))/(2\\\\mu )((\\\\Delta P)/(L))[1-((y)/(Y))^(2)]
\ where
\\\\Delta P
is the pressure change that occurs in length
L
. Calculate average mechanical energy loss
h_(1)
between the pressure gages. Then show that mechanical energy loss also satisfies the equations\
gh_(l)=(\\\\int_(CV) \\\\mu ((delu)/(dely))^(2)dAA)/((m^())), and ,gh_(l)=Re((L)/(Y))((/bar (V)^(2))/(2))
\ where\
Re=(\\\ ho (/bar (V))Y)/(\\\\mu )
