SUMMARY

The discussion centers on calculating the power generated at Hoover Dam using the principles of Bernoulli's law. The dam utilizes water from a depth of 150 meters with an average flow rate of 650 m³/s. Power can be calculated by multiplying the volume flow rate by the energy per unit volume, factoring in the density of water and gravitational acceleration. Participants clarify the components of Bernoulli's equation, specifically addressing the variables involved in determining pressure and energy.

PREREQUISITES
  • Understanding of Bernoulli's equation and its components
  • Knowledge of fluid dynamics principles
  • Familiarity with basic physics concepts such as pressure, density, and gravity
  • Ability to perform calculations involving flow rates and energy
NEXT STEPS
  • Study the application of Bernoulli's equation in real-world scenarios
  • Research the principles of hydroelectric power generation
  • Explore calculations involving energy per unit volume in fluid systems
  • Learn about the impact of flow rate on power generation efficiency
USEFUL FOR

Engineers, physicists, and students in fields related to fluid dynamics and renewable energy, particularly those interested in hydroelectric power systems.

Hoover Dam generates electricity with water taken from a depth of 150m and with an average flow rate of 650 m^3/s.​

Calculate the power in this flow. Note that the velocity and height of the water are not changed appreciably by the generators, and the pressure at the exit point is atmospheric level.

Hint: Power is given by volume flow rate times energy per unit volume.

what have you done up till now ?

i am sure you know how to apply Bernouilli's law

bernoulli's law
is that:
P + 1/2pv^2 + pgy

where little p is the density, g is the gravity, and y is the height? what is the big P?
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
