What is cross-sectional area formula?
Cross-sectional area is determined by squaring the radius and then multiplying by 3.14. For example, if a tree is measured as 10” DBH, the radius is 5”. Multiplying 5 by 5 equals 25, which when multiplied by 3.14 equals 78.5. Thus, the cross-sectional area of a 10” DBH tree is 78.5.
What is the unit of cross-sectional area?
Although the SI unit of total cross sections is m2, smaller units are usually used in practice. In nuclear and particle physics, the conventional unit is the barn b, where 1 b = 10−28 m2 = 100 fm2. Smaller prefixed units such as mb and μb are also widely used.

What is meant by sectional area?
Whereas cross-sectional area is an area which we obtain when the same object is cut into two pieces. The area of that perticular cross section is know as cross sectional area. Suggest Corrections.
What is the difference between area and cross-sectional area?
Area is somewhat that is occupied by an object when it is resting on asurface i.e area is the space which isused by the object. Whereas cross-sectional area is an area which we obtain when the same object is cut into two pieces. The area of that perticular cross section is know ascross sectional area.

How do I calculate wire size?
How do I calculate wire size for motors?
- Multiply the resistivity (Ω•m) of the conductor material by the peak motor current (A), the number 1.25, and the total length of the cable (m).
- Divide the result by the voltage drop from the power source to the motor.
- Multiply by 1,000,000 to get the result in mm2.
How do you find cross-sectional volume?
To calculate the volume of a cylinder, then, we simply multiply the area of the cross-section by the height of the cylinder: V=A⋅h. In the case of a right circular cylinder (soup can), this becomes V=πr2h.
How do you find the minimum cross-sectional area?
To Figure Your Minimum Cross Sectional Area (CA) of your Intake Port. Make all measurements in inches, and convert fractions to decimal numbers. To calculate the cross-sectional area of rectangular and square runner profiles, measure the width and the height of the runner, and multiply the two together.
Is the area of a cross section the same as the base?
The cross section will be the same size as the base. A prism is a polyhedron made up of two congruent, parallel faces (the bases) and sides that are rectangles (lateral faces). For all prisms, cross sections that are parallel to the base are congruent to the base.
Is cross-sectional area the same as diameter?
Litz wire (stranded wire) consisting of many thin wires need a 14 % larger diameter compared to a solid wire. Cross sectional area is not diameter. Cross section is an area. Diameter is a linear measure.
What is the name of a cross-section?
conic sections
Depending upon the relationship between the plane and the slant surface, the cross-section or also called conic sections (for a cone) might be a circle, a parabola, an ellipse or a hyperbola. From the above figure, we can see the different cross sections of cone, when a plane cuts the cone at a different angle.
What is the opposite of a cross-section?
Representing a plane made by cutting across something at right angles to its length. Antonyms. lengthwise vertical inclined.
How do I calculate XLPE cable size?
Calculating voltage drop of this cable, VD = 0.715 MV/A/M, from voltage drop tables. The allowable voltage drop = 415 * 5% = 20.75V. Finally, we can use a cable of Copper, XLPE, 3*50+25 mm2 for the load and laying conditions mentioned above.
How do you calculate kw to cable size?
Ok, let’s dive into calculations…
- Consumed Load = Total Load · Demand Factor: Consumed Load in KW = 80 · 1 = 80 KW.
- Consumed Load in KVA = KW/P.F.: Consumed Load in KVA = 80/0.8 = 100 KVA.
- Full Load Current = (KVA · 1000) / (1.732 · Voltage): Full Load Current = (100 · 1000) / (1.732 · 415) = 139 Amp.
How do you find the area of A cross-section of A circle?
What is cross-sectional area of rectangle?
Cross-Sectional Area of a Rectangular Solid
Therefore, if a cross section is parallel to the top or bottom of the solid, the area of the cross-section is l × w. If the cutting plane is parallel to one of the two sets the sides, the cross-sectional area is instead given by l × h or w × h.
