Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

A horizontal jet of water 2x103 mm2
cross-section and flowing at a
velocity of 15 m/s
hits a flat plate at 60o to the axis (of
the jet) and to the horizontal. The jet
is such that
there is no side spread. If the plate is
stationary, calculate a) the force
exerted on the
plate in the direction of the jet and
b) the ratio between the quantity of
the fluid that
is deflected upwards and that
downwards. Assume that there is no
friction and no
shear force.
