Heya mate here is your answer!!

1 Pascal is defined as when 1 Newton of. force applied per unit area then it is said to be pressure of 1 Pascal .

1 Pascal = 1 newton/ area

⭐You have a pressure of 1 Pascal when a force of 1 Newton is applied on 1 square meter.

⭐A Newton, that’s more or less the weight of an apple on the surface of the Earth.

⭐To give you an idea, the atmosphere constantly applies about one hundred thousand Pascals of pressure on you.

⭐Yep. That’s like one hundred thousand apples per square meter. Or about the weight on Earth of a mass of 10 tons.

⭐This is why you can’t manually open doors in your average airliner when at cruising altitude.

⭐The pressure outside is very low (about 20% of what it is at sea level) and the cabin is pressurized at about 80% of the pressure at sea level. So you get a pressure difference above half of the atmospheric pressure at sea level.

⏩Now on a B737 the doors are usually 1.83∗0.86m2 which is roughly 1.5m2.

⭐This means the airplane’s pressure is pushing the door against the frame with the equivalent force of something that has a mass of 7.5 tons at the surface of the Earth.

⏩Anyway, the Pascal is rather a small unit.

⭐According to Wikipedia, the pressure exerted by a one dollar bill lying flat on a surface (at the surface of the Earth) is around 1Pascal.

⭐A light breeze is already 10 Pascals.
