Water At 10oC (Specific Weight 9.81kN/m3, Density Chegg.com. home / study / engineering / mechanical engineering / mechanical engineering questions and answers / Water At 10oC (Specific Weight 9.81kN/m3, Density

**1000 Kg/m3**, Dynamic Viscosity1.30***10-3**Pa*s,Also to know is, what is the density of water in pounds per cubic foot?

One pint of water weighs one pound (1.04316 lbs/pint). One gallon of water weighs

**8.3453**pounds. One cubic foot of water contains 7.48052 gallons. The weight of one cubic foot of water is 7.48052 gallons times**8.3453**pounds, which equals62.42718356 pounds of water per cubic foot.1

## Why is the density of water is 1?

Just like a solid, the

**density**of a liquid equals the mass of the liquid divided by its volume; D = m/v. The**density of water**is**1**gram per cubic centimeter. The**density**of a substance is the same regardless of the size of the sample.2

## What does a specific gravity of 1.020 mean?

To put it another way, the

**specific**density of water would be 1.000. Ideally, urine**specific gravity**results will fall between 1.002 and 1.030 if your kidneys are functioning normally.**Specific gravity**results above 1.010 can indicate mild dehydration. The higher the number, the more dehydrated you may be.3

## What is the unit weight of reinforced concrete?

In USCS units (United States Customary System units), its weight comes to ~150lb/ft^3 and ~2,400 kg/m^3 if measured in Metric SI system. The concrete calculator is calibrated to exactly

**23.60 kN**/m^3 unit weight per concrete volume. Which is defined as, how heavy is the normal reinforced concrete.4

## What is the density of water at room temperature?

In general, we say that the density of water is

**1000 kg/m^3**(or**1 g/cm^3**). But you're right that it does vary a little bit with temperature. It is exactly**1000 kg/m^3**at 4 degrees Celsius. At 20 degrees Celsius it is**998.23 kg**/m^3 ( or 0.99823 g/cm^3).5

## What is the specific weight of water?

The

**specific weight**(also known as the**unit weight**) is the**weight**per**unit**volume of a material. The symbol of**specific weight**is γ (the Greek letter Gamma). A commonly used value is the**specific weight of water**on Earth at 4°C which is 9.807 kN/m^{3}or 62.43 lbf/ft^{3}.6

## What is the unit slug?

The

**slug**is a derived**unit**of mass in the weight-based system of measures, most notably within the British Imperial measurement system and in the United States customary measures system. A**slug**is defined as the mass that is accelerated by 1 ft/s^{2}when a force of one pound (lbf) is exerted on it.7

## Why is it important to know the specific gravity?

4.1

**Specific gravity**is an**important**property of fluids being related to density and viscosity. Knowing the**specific gravity**will allow determination of a fluid's characteristics compared to a standard, usually water, at a specified temperature.8

## What is specific gravity of urine?

**Urinary specific gravity**(SG) is a measure of the concentration of solutes in the

**urine**. It measures the ratio of

**urine**density compared with water density and provides information on the kidney's ability to concentrate

**urine**. A

**urinary specific gravity**measurement is a routine part of urinalysis.

## Is weight density?

The

**weight**of an object is the force of gravity on the object and may be defined as the**mass**times the acceleration of gravity, w = mg. Since the**weight**is a force, its SI unit is the newton.**Density is mass**/volume.10

## Is density mass?

The

**density**, or more precisely, the volumetric**mass density**, of a substance is its**mass**per unit volume. The symbol most often used for**density**is ρ (the lower case Greek letter rho), although the Latin letter D can also be used.11

## What is the weight of water?

The US gallon, which is equal to approximately 3.785 L, is legally defined as 231 cubic inches. A US liquid gallon of water weighs about

**8.34 pounds**or**3.78 kilograms**at 62 °F (17 °C), making it about 16.6% lighter than the imperial gallon.12

## What is the unit of weight?

The unit of measurement for weight is that of force, which in the International System of Units (SI) is the

**newton**. For example, an object with a mass of one**kilogram**has a weight of about 9.8**newtons**on the surface of the Earth, and about one-sixth as much on the Moon.13

## What is the density of water in kg L?

Many people still use g/cm

^{3}(gram per cubic centimeter) or kg/L (kilograms per liter) to measure density. SI standard is kg/m^{3}. 1 kg/dm^{3}= 1000 g/**1000 cm**= 1 kg/L. The correct SI unit of denstity of water is "ρ =^{3}**1000 kg/m**".^{3}14

## Is specific gravity and density the same?

Because the

**density**of water is 1 g/cm3, it is the most widely used reference substance for determining the**specific**gravities of solids and liquids. The**density**of any substance in grams-per-cubic-centimeter is nearly the**same**numerically as its**specific gravity**relative to water.15

## What is the unit of specific gravity?

Specific gravity is a

**dimensionless**quantity; that is, it is not expressed in units. To find the sp gr of a solid or liquid, you must know its density in kilograms per meter cubed (kg/m^{3}) or in grams per centimeter cubed (g/cm^{3}). Then, divide this density by the density of pure water in the same units.16

## What is the submerged unit weight?

**Saturated unit weight**is equal to the bulk density when the total voids is filled up with water. Buoyant

**unit weight**or

**submerged unit weight**is the effective mass per

**unit**volume when the soil is

**submerged**below standing water or below the ground water table.

## What is the known density of water?

Pure water has a density of

**0.99823**grams/cubic centimeter at 1 atm pressure and a temperature of 20 degrees Celsius (68 degrees Fahrenheit).18

## What is the definition of specific volume?

**Specific volume is**a property of materials, defined as the number of cubic meters occupied by one kilogram of a particular substance. The standard unit

**is**the meter cubed per kilogram (m

^{3}/kg or m.

^{3}· kg

^{-}

^{1}).

## What is specific density?

Relative

**density**, or**specific**gravity, is the ratio of the**density**(mass of a unit volume) of a substance to the**density**of a given reference material.**Specific**gravity usually means relative**density**with respect to water. It is defined as a ratio of**density**of particular substance with that of water.
