Thank you. You're very kind.
Each square centimeter of the flat bottom has (1 x 400) = 400 cubic centimeters of water standing over it.
The mass of 400 cm3 of water is 400 grams = 0.4 kilogram. Its weight is 3.92 newtons, or about 0.88 pounds.
The pressure is
-- 3.92 newtons per square centimeter
-- 0.88 pounds per square centimeter
-- 5.69 pounds per square inch
(all rounded)
Since we are ignoring atmospheric pressure, the pressure at the bottom of the tank is given by p = dgh. Where d equals density, g is acceleration of gravity, and h is the height below the fluid surface. In this case, the density of water is 10^3 kg/m^3, the acceleration of gravity is 9.8 m/s^2, and the height is 4 m. This means the pressure is 39.2 kPa.
The pressure at the bottom of a barrel filled with liquid does not depend on the shape or size of the barrel. It depends only on the depth of the liquid and the density of the liquid.
The human body is well adapted to withstand the atmospheric pressure. Our internal organs and cavities are filled with fluids that apply equal pressure, counteracting the external pressure. Additionally, our body tissues and structures are strong enough to maintain their shape and integrity under normal atmospheric conditions.
The human body resists atmospheric pressure due to the balance of pressure inside and outside the body. Our body tissues, like skin and bones, provide structural support to prevent collapse. Additionally, air-filled spaces within the body, such as the lungs and sinuses, adjust to equalize pressure changes.
P=pgh, remeber that g=9.8 , so ignoring the atmosheric pressure you would just multiply 9.8x4 and you would get 39.2KPa ... i'm not that good with physics so just analyze what is given to you and figure out if the answer is correct or not. Hope I helped :)
Ignoring atmospheric pressure, overall pressure is equivalent to the specific weight of the liquid times the depth. Water has a density of 1 kg/m3 and gravity has a force of 9.81 m/s2. So specific weight = density * gravity = 9.81 kg/m2s2. When multiplied by 4 meters, the answer is 39.24 Pascal's. (1 Pascal = 1kg/ms2).

Elephant. :)
A barometer is the modern meteorological instrument that is used to measure atmospheric pressure. It typically consists of a sealed glass tube filled with mercury that reacts to changes in pressure. The level of mercury in the tube rises and falls depending on the atmospheric pressure.

10.85 psi.
The pressure at the bottom of the tank can be calculated using the formula P = ρgh, where ρ is the density of water (1000 kg/m³), g is the acceleration due to gravity (9.81 m/s²), and h is the height of the water column (4 meters). Plugging in these values, we get P = 1000 * 9.81 * 4 = 39240 Pa, or 39.24 kPa.
A barometer is typically filled with either mercury or a special type of alcohol, such as ethanol or isopropanol. Mercury has traditionally been a common choice due to its density and stability for measuring atmospheric pressure.
Barometers measure atmospheric pressure using two main types: mercury and aneroid. A mercury barometer consists of a glass tube filled with mercury, where the height of the mercury column changes in response to atmospheric pressure; higher pressure pushes the mercury up the tube. An aneroid barometer, on the other hand, uses a sealed metal chamber that expands or contracts with pressure changes, moving a needle on a dial to indicate the current atmospheric pressure. Both types effectively provide a measurement of pressure, though they operate on different principles.
