What Are 3 Quantities Needed To Determine Horsepower?
Describe horsepower and list the 3 quantities needed to determine horsepower. Horsepower is a unit equal to 33,000 ft/lb of work per minute. Force, Distance, and Time.
How do you find specific volume?
It is, therefore, frequently convenient to identify the volume per unit mass of a material as its “specific volume:” v = (V/m). The specific volume is the reciprocal of the density of the material, which is the mass per unit volume: r = (1/v) = (m/V).
Specific volume is inversely proportional to density . If the density of a substance doubles, its specific volume, as expressed in the same base units, is cut in half. If the density drops to 1/10 its former value, the specific volume, as expressed in the same base units, increases by a factor of 10.
What does specific volume mean quizlet?
Specific Volume. a specific volume represents the ratio of the volume of a substance to the volume of an equal weight of another substance taken as a standard (water) at the same temperature.
What direction does a solid exert force?
A solids exert pressure only on its base downwards while a fluid exerts pressure at all points in every direction.
What are the 3 formulas for volume?
The volume of three-dimensional mathematical shapes like cube, cuboid, cylinder, prism and cone etc.
Volume Formulas of Various Geometric Figures.
| Shapes | Volume Formula | Variables |
|---|---|---|
| Rectangular Solid or Cuboid | V = l × w × h | l = Length w = Width h = Height |
What are 3 ways to calculate volume?
Depending on your object shape, you can use different formulas to calculate volume:
- Cube volume = side.
- Cuboid (rectangular box) volume = length × width × height.
- Sphere volume = (4/3) × π × radius.
- Cylinder volume = π × radius2 × height.
- Cone volume = (1/3) × π × radius2 × height.
- Pyramid volume = (1/3) × base area × height.
What are the 3 equations associated with density?
density, mass of a unit volume of a material substance. The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre.
Does pressure affect specific volume?
The Relationship between Pressure and Volume: Boyle’s Law. As the pressure on a gas increases, the volume of the gas decreases because the gas particles are forced closer together.
How do you find volume with only pressure and temperature?
Specific Volume Formulas
ν = RT / PM = RT / P where R is the ideal gas constant, T is temperature, P is pressure, and M is the molarity.
What is defined as the weight per unit volume of a substance?
Weight per unit volume of a substance is called its density.
What are 2 types of energy most frequently used or considered in this industry?
What are the two types of energy most frequently used or considered in this industry? Electrical and heat energy. How were fossil fuels formed?
What property of oil makes it float on water?
The property of oil that allows it to float in water is it’s DENSITY. Oil is less dense than water and dose not mix with water, allowing the oil to float on water.
How does the pressure exerted by a liquid change with depth explain with diagram?
Pressure increases as the depth increases. The pressure in a liquid is due to the weight of the column of water above. Since the particles in a liquid are tightly packed, this pressure acts in all directions.
Did use an expression for the pressure at a depth inside a liquid?
For calculating the total pressure in a liquid at depth, we have to add the atmospheric pressure that acts on the free surface of the liquid. Total pressure inside a liquid at depth ‘h’ = atmospheric pressure + pressure due to the liquid column. So Total pressure inside a liquid at depth = Po + hpg.
What do you mean by the term fluid pressure?
The pressure exerted by a fluid is known as fluid pressure.
What is 3 cubed formula?
An easy way to write 3 cubed is 33. This means three multiplied by itself three times. The easiest way to do this calculation is to do the first multiplication (3×3) and then to multiply your answer by the same number you started with; 3 x 3 x 3 = 9 x 3 = 27.
What does the 3 mean in volume?
Some everyday examples of objects in the shape of a cube are dice, Rubik’s cubes, sugar cubes, gift boxes, etc. The volume of a cube is calculated using the length of its side. Volume of a Cube = a3, where a is the length of each side of the cube.
What are the 2 formulas to find volume?
Perimeter, Area, and Volume
| Table 3. Volume Formulas | ||
|---|---|---|
| Shape | Formula | Variables |
| Cube | V=s3 | s is the length of the side. |
| Right Rectangular Prism | V=LWH | L is the length, W is the width and H is the height. |
| Prism or Cylinder | V=Ah | A is the area of the base, h is the height. |
What 3 tools can be used to measure liquid volume?
Volumetric flasks, burettes, and pipettes made for measuring small amounts of liquid are the most accurate, with tolerances of less than ±0.02.
What are the three 3 base units for length volume and mass?
The metric system uses units such as meter, liter, and gram to measure length, liquid volume, and mass, just as the U.S. customary system uses feet, quarts, and ounces to measure these.
