What is the drag coefficient of a coffee filter?

C=the drag coefficient. I researched this, because in order to calculate it you need a wind tunnel. For a coffee filter, the variable is approximately 1.00(meaning it can be disregarded for this experiment).

How is drag coefficient calculated?

What is the normal drag coefficient?

What is the drag coefficient of a penny?

How do you measure air resistance?

Air resistance can be calculated by taking air density times the drag coefficient times area all over two, and then multiply by velocity squared.

How does the time of fall relate to the weight of the coffee filters?

Students need to recognize that during free fall the drag force is equal to the weight of the filters; therefore, the weight of the filters or number of filters equal drag force during terminal velocity. Best results are obtained by allowing the filters to fall a long distance.

How do you measure aerodynamics on a car?

Drag coefficient

The aerodynamic efficiency of a car’s shape is measured by its co-efficient of drag (generally known as its Cd figure). For example, a flat plate held at right angles to the airflow has a Cd of 1.25, whereas the most efficient production car shapes at the moment have a Cd of about 0.28.

How do you measure the frontal area of a bicycle?

F = 0,5 x ρ x v² x Cw x A

(We took 1,23 kg/m3 as average) v = Velocity in m/s > 100 km/h = 27,78m/s. Cw = Air-resistance value. A = Frontal surface in m2The frontal surface area, is the surface area in m2 that represents the front view of motorcycle including driver.

What car has the least drag?

What is the least aerodynamic car?

You may not think an entry-level luxury sedan could claim the title of the most aerodynamic car. But according to Mercedes, the new A-Class sedan features the lowest drag of any production vehicle in the world, with a coefficient of 0.22. At this level, it defends the world record held by the Mercedes-Benz CLA.

How fast can a penny fall?

The terminal velocity of a penny (aka maximum speed the penny can possibly achieve in free fall) is between 30 and 50 miles per hour, depending on the conditions.

What is the terminal velocity of a cherry?

Average terminal velocity of Riogrand, Orbana and Cherry varieties were measured to be 0.342, 0.108 and 0.076 m.s-1, respectively. The results showed terminal velocity of tomato was increased with increase in fruit volume.

What is the drag coefficient for a coffee filter?

C=the drag coefficient. I researched this, because in order to calculate it you need a wind tunnel. For a coffee filter, the variable is approximately 1.00(meaning it can be disregarded for this experiment).

What is the best shape for a car?

The most aerodynamically-efficient shape for a vehicle is, in theory, a teardrop. A smooth shape minimises drag and the profile, if correctly configured, keeps airflow attached to the surface rather than breaking free and causing turbulence.

What is the drag coefficient of a coffee filter?

C=the drag coefficient. I researched this, because in order to calculate it you need a wind tunnel. For a coffee filter, the variable is approximately 1.00(meaning it can be disregarded for this experiment).

How do you find the aerodynamic drag on a car?

This drag is due to the viscosity of the air. The drag force is generally modeled as: D = 0.5•rho•V^2•S•Cd; where tho is the air density, V is basically the speed of the car, S is the frontal area of the car if we assume that the wake drag is dominant, and Cd is the parasitic drag coefficient.

What do car side skirts do?

Side skirts are the trim panels that are attached to each side of the car just beneath the driver’s and passenger-side doors, offering both protection and increasing aerodynamic performance. Air that moves in from the sides to the underneath of the car (to the chassis) can disrupt the low-pressure front.

What is the fastest vehicle ever made?

Fastest car: Thrust SSC, a super-sonic, jet-propelled car — 763.035 mph (1,227.986 kph). Set on a one-mile track at Black Rock Desert, Nevada in 1997.

Has anyone ever been killed by a penny?

Dropped pennies cannot kill people, no matter how high you drop them from. The reason is that air slows things down. Falling objects reach a maximum speed in air, called the terminal velocity, and can’t go any faster. The less dense an object, the lower its terminal velocity.

Can you survive a jump off the Empire State Building?

Known as one of the tallest skyscrapers in the world, the Empire State Building ranks at a height of around 1,050 feet (320 meters), more than sufficient to get the job done. One lucky person managed to survive a suicide attempt.

How fast will a penny fall?

The terminal velocity of a penny (aka maximum speed the penny can possibly achieve in free fall) is between 30 and 50 miles per hour, depending on the conditions. Using the max 50 mph = 22.35 m/s and the mass of a penny (2.5 g = .
