Answer:
Explanation:
From the question we are told that:
Velocity of water
Height=?
Generally, the equation for Water Velocity is mathematically given by
Therefore Height h is given as
Answer Explanation:
the efficiency of the the engine is given by=1-
where T₂= lower temperature
T₁= Higher temperature
we have given efficiency =70%
lower temperature T₂=27°C=273+27=300K
higher temperature T₁=627°C=273+627=900K
efficiency=1-
=1-
=1-0.3333
=0.6666
=66%
66% is less than 70% so so inventor claim is wrong
