According to Reference.com, "fluid pressure" is defined as the pressure exerted by a fluid at a given depth. The weight of the liquid acting on a unit area combined with pressure acting on the surface of the liquid determines the amount of liquid pressure.Know More
Fluid pressure is affected by pressure and depth. An object placed at higher depth experiences more pressure than a similar object at a lower depth. Fluid pressure is not affected by the volume of liquid, nor can the volume of liquid be changed by pressure. Instead, liquid pressure is dependent on the density of the fluid. Liquid pressure also refers to the pressure exerted by gases. For instance, air pressure in the atmosphere decreases as altitude increases, which is why airplanes have pressurized cabins.
Fluid pressure acts perpendicular to the surface of the liquid and is the force that allows aircraft to fly and ships to float. When determining liquid pressure, the atmospheric pressure on the surface of the liquid must also be taken into account in order to calculate the total pressure of a liquid. A Pascal is a unit of pressure in the metric system that is used to measure the amount of pressure exerted by a liquid.Learn more about Measurements
Girth is defined as the measured distance around an object. In most cases, girth can be found by wrapping a tape measure snugly around the object and marking where the end meets the tape.Full Answer >
One hectare is defined as 10,000 square meters, whereas 1 acre is 4,840 square yards. There are approximately 2.47 acres in 1 hectare. Hectare is a unit of measurement in the International System of Units, while acre is a unit used in the English language.Full Answer >
Density is defined as mass per unit volume, so it is necessary to measure both the weight and volume of an object to determine its density. Use a scale to measure the object's weight. A ruler can be used to measure the dimensions of an object and calculate its volume.Full Answer >
A micron, or micrometer, is defined as one-millionth of a meter. The symbol for micron is μ, an upside-down "h" symbol. A human hair is between 40 and 50 microns wide, whereas a dust mite is about 400 microns long.Full Answer >
