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
According to the University of North Carolina, there are 33.8140226 fluid ounces in one standard liter. Frequently rounded to 33.81 fluid ounces, the number represents a volume measurement for liquids. Fluid ounces and liters are both liquid volume measurements.Full Answer >
The weight of 12 fluid ounces depends on the density of the substance. Twelve fluid ounces of milk weighs 33.94 ounces, but 12 fluid ounces of pure water weighs 12.52 ounces. Salt water weighs 12.84 ounces due to its lower density.Full Answer >
Pressure is calculated as force per unit area. The formula is written as pressure equals force divided by surface area. The unit for pressure, Pascal, can also be written as newtons per square meter based on this relationship.Full Answer >
Barg pressure is the pressure, in units of bars, above or below atmospheric pressure. The "g" at the end of the word indicates that the measurement is not absolute pressure, sometimes indicated by bara. According to The Engineering ToolBox, standard atmospheric pressure is, by definition, 1.01325 at sea-level and 0 degrees Celsius.Full Answer >
