Project Mission
Our goal was to construct a wildlife refuge where
animals are preserved and the public is informed.
Together we researched different features of
wildlife refuges. We attempted to bring together
the positive aspects of different preserves into
one environmentally friendly refuge. This
research included generators, water treatment,
and energy conservation. Our proposal would
also benefit the community by attracting tourists,
creating jobs, and boosting the economy.
What is a Refuge?
• A refuge is a protection or shelter from
danger and hardship.
•Our refuge incorporates exotic wildlife
in an attempt to preserve their
populations from decline and to educate
the public on how and why nature
should be protected.
Benefits of a Wildlife Refuge
• Benefit the community:
– Raising revenue
– Creating jobs
– Drawing in tourism
• Benefit the environment:
– Protecting the natural landscape
– Preserving animals for future generations
• Benefit individuals and families:
– Providing a safe park for all ages
– Providing educational opportunities
– Providing a fun way to exercise through trails
Animals
Physics in Our Project
We found a shark tank at the Mote Marine
Laboratory that holds 135,000 gallons of water.
From there we converted gallons into volume by
using the following formula: (#of
gallons)(0.134feet3/1 gal)= Volume
Our tank has a volume of 18,090 feet 3.
From this point we found the area of the tank by
dividing the volume by the height (25ft). We
then found the radius/diameter of the tank. Our
shark tank is 25 feet high and has a diameter of
30.36 ft.
Pressure
From this point we needed to figure out how thick the
glass would need to be to contain this much water.
Pressure is proportional to density times depth times
gravity plus air pressure. *The density of saltwater is
1,025 kg/m3, and air pressure equals 1.01x105N/m2. So,
the pressure exerted on the glass at the deepest point of
the tank is 77,045.15 plus 1.01x105N/m2. Or (if my math
is correct) 178,045.15Pa.
So, we would need a glass that could contain water
exerting this much pressure. Pyrex glass, according to
Young’s Modulus, can hold a unit of force per area that
equals 62 billion N/m2.
2 smaller walk-through tanks
•
If we have two smaller aquariums that people could walk through (one saltwater,
and one freshwater) we would need to know the pressure of the water on the glass.
As we go deeper in the tank the pressure increases. The dimensions of the tank
would be 12 ft. high, by 24 ft long, by 12 ft. wide, with a 9 ft by 3ft cut out. The
volume of one tank equals 2,808 feet3. Each tank holds 20,955.22 gallons of water.
Freshwater (density=1000kg/m )
Seawater (density=1025kg/m )
The freshwater tank exerts a pressure
of 140,200Pa.
The saltwater would exert a pressure
of 141,180Pa
2
(1000kg/m3)(4m)(9.8m/s2)=
39,200+ 1.01x105N/m2= 140,200Pa
2
(1025kg/m3)(4m)(9.8m/s2)=
40,180+ 1.01x105N/m2= 141,180Pa
*We would need to use a glass (or
synthetic glass) that would be able to
sustain at least 141,200Pa with out
reaching a fracture point.
Force
By using the Impulse/Momentum
Theorem, we concluded that an elephant
moving at its maximum speed of 55 m/s
and having a mass of 1203 kg will exert a
force of 66 kN. Meaning, we would need
an enclosure that could withstand up to
15,000 lbs. of force. The walls of the
enclosure would need to be made of
concrete, 4 feet thick, with steel bar
reinforcement.
Work
Our land is 1,200 acres. To make this easier, we will assume the perimeter is a
rectangle. The dimensions of the land are 435,600ft long x 144,000ft wide… that’s 82
miles long, and 27 miles wide! We will set the park up, so people can walk through
and see the animals in cages (5 miles), or go on a longer trail on a bike or golf cart and
see the animals in free-roaming areas, which will have more animals, and more space
for them to move (this will be approximately 25 miles long).
Riding a bike has the best over all efficiency…
A personriding a bike will have an efficiency of 1,100 kg-km/megajoule
walking will have an efficiency of 300 kg-km/megajoule
riding in a golf cart 40 kg-km/megajoule
The efficiencies can best be compared expressed as ratios:
riding a bike and walking- 11:3 kilogram-kilometers per megajoule
walking and riding in a golf cart- 30:4 kilogram-kilometers per megajoule
riding a bike and riding a golf cart- 110:4 kilogram-kilometers per megajoule
Energy
• As a monkey swings from one branch to another
it has both Potential and Kinetic Energy. The
monkey first starts off with maximum Potential
Energy, with 0 velocity. Then as it swings it uses
both Kinetic and Potential Energy, and as it
reaches the midway point it hits its maximum
velocity and Kinetic Energy. It then continues
with both Potential and Kinetic, and once it has
made it to the final destination it will again
reach its Potential Energy maximum.
Park Specialties
• Our Wildlife Refuge will be located on
1200 acres of land in Green Forest, AR .
Features include a numerous amount of
exotic animals, a reptile hall, a walk
through aquarium, and lunch and picnic
areas will be all throughout the refuge.
Bikes and golf carts will be available for
rent, and educational tours will be given
daily to truly experience what all the
refuge has to offer.
