Energy of Aerodynamics Flashcards
There is a ____________ between running speed and oxygen consumption
positive linear relationship
Oxygen consumption is a _______________ to mammalian weight
negative linear relationship
Small animals ______________
consume more oxygen per unit distance
Humans are very inefficient mammals. This is because we are _____________
bipedal
What is is the order of the energy of movement
swimming
Why s swimming low energy
- they can glide not fly
- can use inertia
Why is flying middle energy
- can use inertia sometimes
- can use the wind dont always have to use muscles
Why is running high energy
-muscle must alway contract and flight gravity
Insect flight is still the most energetically costly because
they can not glide. They do not have enough inertia
The energy necessary for flight varies the most as there as been
the most adaptation for flight including aerodynamics
what is the physical factor that affect locomotion
Reynolds number, the transition from laminar flow (viscous forces) to turbulent flow (inertia)
what is Reynolds number
inertia forces over viscous forces
When there is wind what happens to flight speed
the speed is aded to the speed on top of the wing
The pressure forces acts _________
orthogonal to the wing
when the wing is angle relative to the oncoming flow, more fluid travels over the ___________
he top than the bottom
