## What is the estimated volume of an inflated football?

We’ll assume that the footballs were inflated at a temperature of 68 degrees Fahrenheit, which is consistent with the interior thermostat setting recommended by the U.S. Department of Energy for optimal personal comfort and low energy consumption in the winter, the gametime temperature of 51 degrees Fahrenheit, the …

How do you find the volume of a American football?

Stick the football down completely into the water without getting your hand in the water. After doing so, remove the smaller water-filled bucket and measure how much water spilled out into the bigger bucket. That’s the volume of the football.

What is the correct air pressure for a football?

between 8.5 psi and 15.6 psi
In its section on rules about “The Ball,” it states that they must be spherical and inflated to a pressure between 8.5 psi and 15.6 psi. When a soccer ball is inflated with less than 8.5 psi, it is more difficult to kick and send down the field and is considered too flat.

### What is the volume of a football?

We can compare this with the volume of a football (soccer ball) – which has a radius of around 10.5cm, therefore a volume of around 4800 cubic centimeters.

What is the estimated density of the inflated football?

(using the density of helium and volume both at standard atmospheric pressure). The Mythbusters found that helium-filled footballs are 7 grams lighter than an air-filled ones, but their calculations seem incorrect….Density: Floating Footballs.

Substance Density (g/cm3 at 20oC)
Sulfur hexafluoride 0.006164
Argon 0.0018
Halon 1301 0.0066
Water 1.00

What is the volume of a football field?

An American football field is 120 yards by 53 \large \frac13 yards (including the end zones). If you covered a football field with this radioactive waste to the height of the goal post cross bar, 10 feet, this would give you a volume of 21,333.2 cubic yards.

#### What pressure should a size 4 football be?

6-8 psi
A size 4 football measures between 63.5 and 66cm in circumference and should weigh between 340 and 390g. When pumping up a size 4 football Mitre recommend that they should be inflated to a pressure of 6-8 psi (0.42 – 0.56 bar) for training balls and 7-10 psi (0.49 – 0.70 bar) for match balls.

What is the density of a football?

What is the volume of a football in cubic centimeters?

## What is the pressure inside an NFL football?

Luckily, we evolved in Earth’s atmosphere and our cells have interior pressures just above 14.7 psi, so we feel equal forces on each side of our skin. The legal total pressure inside an NFL football is thus 27.2 psi – 28.2 psi. Assume that an NFL football is at 13 psi when checked inside a locker room at 70 F (21 C or 294 K).

What happens to the air inside of a football?

Inside a football, air molecules bounce around and collide with the interior walls of the ball (bladder, really). The air’s pressure inside a football will go down with temperature.

What are the dimensions of a football?

The length should measure about 11 inches from tip to tip, and the in circumference at the center of the football should measure about 22 inches. Weight. Overall weight and air pressure are specific in the NFL, too. The football and materials weighs about 14 to 15 oz., and is the ball is inflated to about 12.5 to 13.5 lbs. per square inch.

### How much does an NFL football weigh?

Overall weight and air pressure are specific in the NFL, too. The football and materials weighs about 14 to 15 oz., and is the ball is inflated to about 12.5 to 13.5 lbs. per square inch. These weight and air pressure measurements create consistency among the many footballs required in a game.
