Question
Consider a situation wherein water is flowing from the top of waterfall
that is 130 m high.
This phenomena in nature is a good example of an energy transfer : the
potential energy of water at the top of the waterfall to kinetic energy of
the water just before the water strikes the bottom of the waterfall with
the consideration that the water does not exchange energy with its
surroundings which is a good example of a closed system. It means that
there is a 100% energy conversion.
Taking a basis of 1 kg of water as the thermodynamic system in this part
of the universe and g as 9.81 m/s?, the kinetic energy of 1 kg of water in
Joules is
O 1,079.1
O 1,275.3
981
O 1,030.05
