Is specific gravity specific weight?
Specific gravity is a dimensionless quantity whereas specific weight has dimensions. The specific gravity of a material is independent of the gravitational field, but the specific weight of a material is dependent on the gravitational field.
How do you convert kg to liters with specific gravity?
To convert a kilogram measurement to a liter measurement, divide the weight by the density of the ingredient or material. Thus, the weight in liters is equal to the kilograms divided by the density of the ingredient or material.
Is specific gravity and unit weight same?
The specific weight, also known as the unit weight, is the weight per unit volume of a material. The terms specific gravity, and less often specific weight, are also used for relative density.
How do you calculate estimated weight?
Three simplified linear equations were derived to calculate mean weight for age. For Infants < 12 months: Weight (kg) = (age in months + 9)/2 For Children aged 1-5 years: Weight (kg) = 2 x (age in years + 5) For Children aged 5-14 years: Weight (kg) = 4 x age in years.
How to calculate volume using specific gravity?
How to Calculate Volume Using Specific Gravity Obtain the specific gravity of the liquid using a refractometer, digital density meter, hydrometer, or a reference chart. Determine the mass of the substance (weigh it using a gram scale) or assign a fictitious amount that is convenient (such… Assign the values in the formula and solve for V (volume). For… See More….
How to calculate density from specific gravity?
First,determine the specific gravity. For this example,we will say the specific gravity is 50.
What is the difference between density and specific gravity?
Density and specific gravity are both indications of how much mass a substance would occupy in a given volume. The main difference between density and specific gravity is that density is the mass per unit volume of the substance whereas specific gravity is a ratio comparing the density of one substance to the density of another reference substance.
What is the formula for specific weight?
Specific Weight. the ratio of a body’s weight P to its volume V—that is, the quantity γ = P/V. Specific weight can also be determined from the formula γ = pg, where p is the density of a substance and g is the acceleration of free fall.
