Specific gravity of water

New York Board of Health has a scale graduated into 120 equal parts, 0° being equal to the specific gravity of water and 100° being equal to a specific gravity of 1.029. 

In this study the concentration of the water in the grid is adjusted to correspond to the density (specific gravity) of water at various temperatures. These adjusted concentrations are shown in Table 3.1. Run the example 3.2 for the adjusted concentrations of water in Example 3.2 in the program CASim for a temperature of 20°C. 

In the SI system, the theoretical unit of v is m2/s or the commonly used Stoke (St) where 1 St = 0.0001 m2/s = 100 cSt = 100 centiStoke. Similarly, 1 centiStoke = 1 cSt = 0.000001 m2/s = 0.01 Stoke = 0.01 st. The specific gravity of water at 20.2°C (68.4°F) is almost 1. The kinematic viscosity of water at 20.2°C (68.4°F) is for all practical purposes equal to 1 cSt. For a liquid, the kinematic viscosity will decrease with higher temperature. For a gas, the kinematic viscosity will increase with higher temperature. Another commonly used kinematic viscosity unit is Saybolt universal seconds (SUS), which is the efflux time required for 60 mL of petroleum product to flow through the calibrated orifice of a Saybolt universal viscometer, as described by ASTM-D88. Therefore, the relationship between dynamic viscosity and kinematic viscosity can be expressed as...

As is the specific gravity of turpentine to the. specific gravity of water, so is the observed bulk of turpentine to an equal bulk o water. 

Specific gravity The weight of a sohd or hquid substance as compared to the weight of an equal volume of water specific gravity of water equals 1. 

First, solve for the specific weight of the oil. The specific weight of water is assumed to be 62.41b/ft. The specific gravity of water is 1.0. The specific weight and specific gravity for a fluid have a constant ratio, the force of gravity. 

The 2.3 ft/psi factor assumes that the specific gravity of water is 1.00. 

Caution Some texts will show you that the kinematic viscosity in centistokes is equal to the viscosity in centipoise divided by the specific gravity. This can be numerically correct only for centipoise and centistokes because the density of water (to which the specific gravity of all liquids is related) in the cgs system is 1 g/cm , which is numerically equal to the specific gravity of water, which is also 1.0 at standard conditions. It would be far better practice to use density throughout and be certain to use consistent units in all your calculations.
