Energy and Its ConservationProblem of the Week (0.0K) | (0.0K) | (0.0K) | The
power of the nuclear reactor is 190 MW.
The power delivered to the propeller is 43 000 hp. | | (0.0K) | | Efficiency
is the ratio of energy output to energy input. | | (0.0K) | | (0.0K) | To
determine the energy due to motion, use the kinetic energy equation,
(0.0K):
| | (1.0K) | | To
calculate time, use the definition of power, (0.0K):
| | (0.0K) | | Because
the sub takes much longer to accelerate, much of the energy
from the propulsion must go into stirring the water and other
energy drains. | | (0.0K) | (0.0K) | (0.0K) | (0.0K) | (0.0K) |
