How Do You Measure Television Screen Size?
How Do You Measure Television Screen Size? To measure television screen size, place the hook of a retractable tape measure at one corner of the screen and pull the measure diagonally across the screen. Measure the corners of the screen rather than the bezel of the television. Place the tape measure on the upper left-hand corner Hold the hook of the tape measure on the upper left hand corner of the television screen, just inside the bezel of the TV. Pull the tape measure While holding the hook at the upper left hand corner, pull the tape measure diagonally across the screen. Stop at the edge of the screen, just inside the bezel of the television. Record the number The tape measure component marks the length of the television screen. Record the number that the tape measure is showing.
Display size - Wikipedia
The method of measuring screen size by its diagonal was inherited from the method used for the first generation of CRT television, when picture tubes with circular faces were in common use. Being circular, the external diameter of the bulb was used to describe their size. Since these circular tubes were used to display rectangular images, the diagonal measurement of the visible rectangle was smaller than the diameter of the tube due to the thickness of the glass surrounding the phosphor screen (which was hidden from the viewer by the casing and bezel). This method continued even when cathode ray tubes were manufactured as rounded rectangles; it had the advantage of being a single number specifying the size, and was not confusing when the aspect ratio was universally 4:3. In the US, when virtually all TV tubes were 4:3, the size of the screen was given as the true screen diagonal with a V following it (this was a requirement in the US market but not elsewhere). In virtually all other markets, the size of the outer diameter of the tube was given. What was a 27V in the US could be a 28" elsewhere. However the V terminology was frequently dropped in US advertising referring to a 27V as a 27". This was not misleading for the consumer as the seller had to give the actual screen size by law. Flat panel displays by contrast use the actual diagonal of their visible display size, thus the size is the actual size presented to the viewer in all markets. This means that a similarly specified size of display will be larger as a flat panel display compared with a cathode ray tube display.
What is foremost when looking to buy a laptop?
the number of usb ports, operating system, keyboard & screen size, weight; is a wifi card included, battery life
Im comparing two laptops, the processor, screen size, and hard drive space are the only differences.?
Harddrives are upgradable. pc monitors are not. you should get the single with the bigger demonstrate screen and installation a larger hard disk drive. Toshiba makes a 200GB pc hard disk drive. and of direction in case you honestly need extra storage you should get an exterior force. you will get a 500GB USB exterior hard disk drive for basically $200 by way of NewEgg. super exterior harddrives in lots of cases require AC skill nonetheless meaning they wo not be usable on the circulate
Wye Strainer Mesh and Screen Sizing Guide
To find the wye strainer that is right for your project or job, it's important that you know how mesh and screen sizing works. While deciding which size strainers to purchase, you need to consider both the micron and mesh values. Use our Micron and Mesh Comparison Chart to determine the best strainer for you. Micron and mesh size are measurements that are used to describe different sizes of wye strainers. While these two types of measurements are expressed differently, they both describe the same thing - the measure of the size of the openings in the strainer that materials pass through. The mesh or micron size will tell you what size particles will be stopped, or strained, from the liquid flowing through the strainer. Micron is short for micrometer. It's a unit of length that is used for measuring very small particles. A micrometer is defined as one-millionth of a meter which is equivalent to about one twenty-five thousandth of an inch. The micron value of a wye strainer indicates the size of particles it will filter out. What Does Mesh Size Mean? Mesh size is fairly straightforward. It measures the number of openings in the mesh that make up one linear inch. For example, a 12 mesh screen means that there 12 openings across one inch. A 120 mesh screen means the openings are much smaller and that there are 120 openings per inch. The higher the mesh number, the bigger the particles that are allowed to pass through the strainer. As you can see, microns and mesh size measure the same thing, but differently. Micron measurements tell you the size of the opening in the strainers, thus what size particles it will capture. Mesh size tells you how many openings there are in an inch, which can be calculated to provide you with the same information. The following chart will help you understand mesh sizing in more detail. For example, a size 12 mesh screen has openings that are 1680 microns and a size 100 mesh screen has openings that are 149 microns. When the mesh screen size gets to higher than 400, measurements are typically expressed in microns only. At those sizes, it's the most accurate way to measure. Size is Determined on an Individual Basis Because wye strainers are used in various industries, the material of the strainer and the size of the mesh screen that is used for a project or job have to be determined on an individual basis. The type of pipe system, the material that is used in the system, the size of the unwanted particles to be captured, and the pressure and temperature involved in the system are all considerations to keep in mind as you decide which wye strainer is best. One thing to keep in mind about mesh sizes is that they are not exactly precise. Screens are constructed with different materials. That means that there are different thicknesses of the wires or strands depending on the material. In other words, the thicker the material, the smaller the openings will be.
