The specific weight and the fluid density are related by the acceleration due to gravity, or The pressure exerted by a static fluid depends only upon. For gases the specific weight - varies with elevation (and compression). Its units in the English system and the SI system are lb/ft³ and N/m³ or kg/m² density of fluid (kg/m 3, slugs /ft 3 ) g acceleration of gravity (9.81 m/s 2, 32.174 ft/s 2 ) In general the specific weight - is constant for fluids. It is usually denoted by the Greek letter γ (gamma) and has dimensions of force per unit volume. Specific weight, sometimes referred to as unit weight, is simply the weight of fluid per unit volume. The density of water is 1.94 slug/ft³ or 1000 kg/m³ (1 gr/cm³) The gallon now equals the space occupied by 10 pounds of distilled water of density 0.998859 gram per millilitre weighed in air of density 0. It is possible to convert between the English system and the SI system by substituting the equivalent of each dimension with the appropriate value. The units of density in the SI system are kg/m³ or N The units of density in the english system are Slug/ft³ or lb Since the units of acceleration are ft³/sec² F(force) = M(mass) x g(acceleration due to gravity) By using the LFT dimension the slug can be obtained by relating mass to force with acceleration due to gravity. In the Systeme International (SI), the common dimensions are mass, M, length, L, and time, T. Dimensions commonly used in connection with this system are force, F, length, L, and time, T. The old English system of units uses the slug for the unit of mass and feet for the unit of length. The dimensions of density are mass per length cubed or M / L³ Otherwise, we would have 10 hours/day, 100 minutes/hour, and 100 seconds/minute.Įdit: And what is with 360 degrees instead of 100? Of course that would have changed the Nautical mile.Fluid Density is the mass per unit volume and is denoted by the Greek letter ρ (rho). It is too bad that the availability of time pieces was so widespread in the 1700s. Time itself is another victim of bad timing. The Nautical mile is probably the only pre-Metric unit that will survive, at least as long as anyone remembers how to navigate beyond looking at a GPS. The Nautical mile was also based on natural or earth units and was no less precise than they were capable of measuring the length of a meridian in those days. It is more complex than that and an interesting story but that was the net effect. That delay significantly hurt the promoters in the early US government that were pushing the metric system. The worse part was the lame attempt to survey that meridian delayed the definition of the Meter by years. It ended up being inaccurate and had to be redefined a few times anyway. They should have used a decimal fraction of a Nautical Mile instead of one ten-millionth of the distance between the North Pole and the Equator along the meridian through Paris. In hindsight, the Meter, or Metre, was really a mistake. It was just bad timing and the distance between markets. The irony is the US is still suffering from the units that you Brits stuck us with! Just joking. Find the density of water in various units of measurement, such as kg/m³, lb/ft³, g/ml, and more. ![]()
