# How Much Force Does It Take To Crush A 55 Gallon Drum?

## Why are we not crushed by air pressure?

Answer 5: It’s true that the weight of the column of air above us is very heavy.

However, the reason we, nor other objects, are crushed by the weight of this air is because this external pressure is balanced by our internal pressure, which arises from various fluids and materials we are composed of..

## How much pressure can a 55 gallon drum take?

Standard water pressure around here is roughly 40 psi or so. Assuming a 55 gal drum has a diameter of 18″ (9″ radius) – this means the end of the drum has an area of about 250 sq. in. 40 psi will exert a force of about 10,000 lbs on the end of the drum.

Places to look for free 55-gallon drums include beverage manufacturers, car washes, Craigslist, hardware stores, industrial waste collection companies, insulation companies, and landfills.

## Can the ocean crush you?

Human beings can withstand 3 to 4 atmospheres of pressure, or 43.5 to 58 psi. Water weighs 64 pounds per cubic foot, or one atmosphere per 33 feet of depth, and presses in from all sides. The ocean’s pressure can indeed crush you.

## At what depth will water crush you?

Human beings can withstand 3 to 4 atmospheres of pressure, or 43.5 to 58 psi. Water weighs 64 pounds per cubic foot, or one atmosphere per 33 feet of depth, and presses in from all sides. The ocean’s pressure can indeed crush you.

## Can you swim down to the Titanic?

The trip to Titanic’s resting place takes about 2.5 hours, and a round-trip dive lasts about 8 to 10 hours. … (See pictures of Titanic then and now in National Geographic magazine.) But summer 2012 is the first season since 2005 that Deep Ocean Expeditions has taken people to the Titanic—and it could be the last.

## What is crush depth for a human?

In short: most of the body can handle any pressure, but if we’re breathing air the maximum safe depth is about 60 meters (190 feet), the feasible maximum with current technical capabilities (and special breathing gases) is about 500 meters (but, for safety reasons, those depths have only been simulated).

## Is it safe to pressurize a 55 gallon drum?

I agree that 5 psi is a conservative maximum. After all, a 55 gallon drum isn’t an ASME pressure vessel. According to this paper they say the drums can withstand up to 14psi, at which point the open head drums they are talking about self-vent. However, the drum will significantly deform (ends bulging) at 6-8psi.

## Can crushing experiment air pressure?

When the soda can is placed upside down into a bowl of cold water, the cold water causes the gas to cool and condense into a liquid, decreasing the pressure inside the can. The air pressure outside the can is much greater than the pressure inside the can, so it pushes the can inwards, “crushing” the can.

## How long is a 55 gallon drum?

Many drums have a common nominal volume of 208 litres (55 US gal) and nominally measure just under 880 millimetres (35 in) tall with a diameter just under 610 millimetres (24 in) and differ by holding about 49 litres (13 US gal) more than a barrel of crude oil.

## How much water pressure can you get from a rain barrel?

What kind of water pressure can I expect from a Rain Barrel? The higher the elevation, the greater the water pressure will be at its lowest point. Each foot in elevation change is equal to 0.433 PSI (pounds per square inch) of water pressure. So, if you place your barrel on a 3 ft.

## How much pressure can a soda can hold?

Modern aluminum cans are less than a tenth of a millimeter thick, yet hold liquid at up to 90 pounds per square inch (about six times regular atmospheric pressure).

## Can crushing experiment Gas Law explanation?

Discussion: Boyle’s Law describes the relationship between volume and pressure of gases. … When immersed in water, the water seals the opening and the vapor inside the can condenses, thus reducing the pressure inside the can and causing the can to be crushed. Safety: Boiling water can cause burns.
