2. A 15 mm diameter jet of water impinges normally at the centre of rectangular plate of size 100 mm x 100 mm x 4 mm with a velocity of 5 m/s. The top edge of the plate is hinged. Determine the force required to apply at the bottom edge to keep the plate vertical. What would be the angle by which the plate is deflected in the absence of resisting force? The density of plate material 3 is 7850 kg/m².

Subject: Fluid
Transcribed Image Text:2. A 15 mm diameter jet of
water impinges normally
at the centre of
rectangular
plate of size 100 mm x
100 mm x 4 mm with a
velocity of 5 m/s. The top
edge of
the plate is hinged.
Determine the force
required to apply at the
bottom edge to keep the
plate vertical. What
would be the angle by
which the plate is
deflected in the absence
of resisting force? The
density of plate material
is 7850 kg/m".
3. Pelton wheel runner
produces 20 MW under a
head of 450 m when
running at a speed of
600 rpm. If the mean
runner diameter is 10
times the diameter of jet,
determine the number of
jets, diameter of each jet,
diameter of wheel, and
discharge. The overall
efficiency, coefficient of
velocity, and speed ratio
are 0.85, 0.98, and 0.47,
respectively.
