What is cross sectional area Quora Aug 18 2017 · Cross section area is an area of an object if you view it as a 2D object. For example imagine a perfectly rounded ball. If you look at the ball and view it as 2D object you will see a circle Cross section area is an area of an object if you view it as a 2D object.
Even flow is achieved due to the gradually decreasing cross-sectional area of the casing. As the cross-sectional area decreases, the velocity of the water in the case is maintained and an even flow of water is delivered to the runner. Francis Turbine Scroll Case. Guide vanes direct water towards the runner. The purpose of the guide vanes is to ...
Oct 27, 2019· Sectional density is defined as a bullet's weight (mass) divided by its cross sectional area. Do the math and the resulting number is called the bullet's sectional density or SD. In plain English, the heavier a bullet in any caliber (diameter,) the higher its SD. And the higher its SD, the better it will retain momentum.
Notes: The formula for calculating allowable current through a trace is published in the IPC-2221 standard section 6.2 as shown below. Internal traces : I = 0.024 x dT 0.44 x A 0.725 External traces: I = 0.048 x dT 0.44 x A 0.725 Where I is maximum current in Amps, k is a constant, dT is temperature rise above ambient in °C, & A is cross sectional area of trace mils².
Note—Size numbers (in.) are the nominal cross-sectional area of the wire in hundredths of a square inch. Fractional sizes between the sizes listed above are also available and acceptable for use. 2.7. Epoxy Coating. Provide epoxy coated reinforcing steel as shown on the plans. Before furnishing epoxy
A refers to cross-sectional area of copper trace with its unit to be square mil (mil²). I refers to current carrying capacity with its unit to be ampere (Amp). Owing to the development of electronic technology, some online trace width calculators are available for circuit board designers. It's such a handy tool that as soon as demanded current ...

This study aimed to investigate the relationship between the maximal anatomical cross-sectional area (ACSA) of the iliopsoas muscle and ball speed in side-foot and instep kicks. The ACSA of the psoas major and iliacus was measured in 29 male collegiate soccer players by using magnetic resonance imag .
The formula for the terminal velocity of a falling object (V t) can be calculated from the body's mass m, the density of the fluid in question (p, in kg/m 3, e.g. 1.225 for air), the cross-sectional area projected by the object (A), and the gravitational (or equivalent) force g in m/s 2 according to the following equation:
Mar 05, 2018· Cross-sectional area will depend on the orientation of your intersection plane. It's like measuring a pin's diameter with a pair of calipers. If you don't hold the calipers just right, you'll end up with a value larger than the actual diameter. Other than trial and error, I don't know of a good way to define find the proper intersecting plane.
In this formula, A (area) is the unknown and is equal to the cross-sectional area in square mils, π is the constant 3.14, and r is the radius of the circle, or half the diameter (D). Through substitution, A = 3.14, and (12.5) 2; therefore, 3.14 X 156.25 = 490.625 square mils. The cross-sectional area of the wire has 625 circular mils but ...
The drag force, F D, on a ball increases with the square of the velocity, v, assuming that the density, r, of the ball and its cross-sectional area, A, remain unchanged: F D = C D r Av 2 /2. It appears, however, that the "drag coefficient", C D, also depends on the velocity of the ball.
(a) cross sectional haadf stem image of as milled mgh2 (gray color) with 1 mol% nbf5 (white color) after ball milling time of 15 min, (b) saed pattern from.3 is a cross sectional view of a liner section shown in relaxed condition prior to mounting in a ball mill; fig.
The cross-sectional area of the mill charge (A C) can be determined from: A↓C = H↓B / 6W (3H↓B↑2 + 4W↑2) Since the cross-sectional area of the mill is simply πR 2, the mill volume fraction occupied by the media charge is:

cross section of a baseball A baseball has a cork core, which is wrapped in layers of rubber, wound with yarn and covered with leather. ... Outer layer of the ball made up of two white pieces of leather joined by stitching. cork ball Small sphere of cork that forms the central part of the ball. yarn ball Yarn wound around the center of the ball
The maximum load per unit of initial cross-sectional area obtained before rupture in a tension test. Tensile Test. A tension-testing machine mechanically or hydraulically applies a tensile load to a specimen. The test establishes ultimate strength, yield strength, and ductility (elongation and reduction of area). Torch Cutting
a golf ball because it is has a higher weight to cross sectional area ratio. ( weight to drag ) The inverse of this is why a bean will fall faster than a feather of the same weight.

A = 2.343 * 10-4 m 2 A = 2.343*10^{-4}m^{2} (cross sectional area of a paintball) C d = 0.47 C_{d} = 0.47 (drag coefficient for a smooth sphere) ∅ = 0.017272 m empty = 0.017272m (diameter of a paintball)
Feb 07, 2020· To calculate the cross-sectional area of a plane through a three-dimensional solid, you need to know the precise geometry of the solid and the angle the cutting plane makes with the solid's axis of symmetry, if any. The area of cross-sections have unique formulas depending on the solid.
Apr 07, 2020· A cylindrical copper rod of length 1.2 m and cross-sectional area 4.8 cm2 is insulated along its side.The ends are held at a temperature difference of 100 C by having one end in a water–ice mixture and the other in a mixture of boiling water and steam.
The size of a target's image on radar is measured by the radar cross section or RCS, often represented by the symbol σ and expressed in square meters. This does not equal geometric area. A perfectly conducting sphere of projected cross sectional area 1 m 2 (i.e. a diameter of 1.13 m) will have an RCS of 1 m 2. Note that for radar wavelengths ...
