A square yard is a measurement in 2 dimensions, length and width. Since there is no depth measurement in a square yard, therefore, a square yard of water has no weight. However, "...a cubic yard is 27 cubic feet, and a cubic foot of water weighs about 62.4 pounds, so 62.4 x 27 gives you...about 1685 pounds." (http://saluqi.home.netcom.com/ticklinx1.htm)
That is an unanserable question. Square foot means an area and for a weight you need at least a volume.
To have weight it must also be a three dimensional unit, things don't have weight in the flatlands. A cubic foot of water weighs 62.42796 Pounds. A cube is the three dimensional version of a two dimensional square, a foot of depth being the difference between a square and a cube.
approx. 3,8 kg.
Water pressure increases with depth due to the weight of the water above exerting force down onto the water below. The greater depth results in a larger column of water pressing down, leading to higher pressure levels. This increase in pressure is proportional to the depth underwater.
The weight of sea water really depends on a number of variables, including the temperature, the amount of salt (salinity) and whatever other foreign items may be present, and the depth, thus the pressure. But to get to the basic answer, seawater, at the surface, on average weighs 1027 kg/m3, or just over 64.1 lbs per cubic foot. ----------- The question is another way of asking for density of salt water. Salt water has greater density than that of fresh water, due to the dissolved salt. Fresh water has a density of 1000 kg/cubic meter vs. an average density of 1027 kg/cubic meter for ocean salt water.
Sea water is typically around 3.5% salt by weight, or 35 parts per thousand. This salinity can vary based on location and factors like evaporation and precipitation. It is this salt content that gives sea water its characteristic salty taste.
The weight that 1 cubic foot of air can support depends on the density of the air. At sea level and room temperature, 1 cubic foot of air can support approximately 0.08 pounds. However, this value can vary based on factors such as altitude and temperature.
One cubic foot of sea water contains about 7.5 gallons.
About 2.2 pounds of salt in a cubic foot of sea water. There are about 7.48 gallons in a cubic foot and sea water weighs about 8.5 pounds per gallon (63.58 pounds). Sea water is about 3.5 % salt (usually reported as 35 ppt or parts per thousand). So 63.58 x .035 = 2.2 pounds of salt.
We know that the density of the sea water is more than the density of the river water. So, the weight of displaced sea water is more than the weight of displaced river water. This weight gives the upward Buoyant force to the swimmer. Thus, the apparent weight of the swimmer is less in the sea water. Hence he finds it easier to swim in the sea water.
33.2 cubit meters !!
33 but usually 28
approx. 3,8 kg.
The weight of the sail boat is less than the weight of the water it displaces. That is its density is less than that of water.
Sea pressure is caused by the weight of the water above exerting force on a specific point in the ocean. The deeper you go in the ocean, the greater the amount of water above, leading to higher pressure. This pressure is typically measured in units such as pounds per square inch (psi) or atmospheres.
14.7 pounds per square inch at sea level.
The Caspian Sea is the largest enclosed body of water at 143,244 square miles.
Water pressure increases with depth due to the weight of the water above exerting force down onto the water below. The greater depth results in a larger column of water pressing down, leading to higher pressure levels. This increase in pressure is proportional to the depth underwater.
Pressure 1 mile below sea level is approximately 1,525 pounds per square inch (psi). This is due to the weight of the water column above exerting pressure on the depth below.
