Kniited goods are usually measured by roll weight rather than their length .
Points/100sq yds>> ( GSM x 0.082 x total points of that roll ) / roll weight in kgs

after inspection of fabric based on 4 point system how to calculate the % of fabric pass or fail
The 4-point fabric inspection system is a quality control method used primarily in the textile industry to assess fabric defects. Under this system, defects are categorized based on their severity and the size of the area affected. Each defect is assigned points: 1 point for minor defects (less than 1 inch), 2 points for medium defects (1 to 3 inches), 3 points for major defects (3 to 6 inches), and 4 points for critical defects (over 6 inches). The total points accumulated from the defects found in a specific length of fabric determine its quality rating, guiding manufacturers in making decisions about fabric usage and potential rework.
Point Slope Formula: y-y1 = m(x - x1)
The midpoint formula is used to find the point that is in the middle of a segment.

after inspection of fabric based on 4 point system how to calculate the % of fabric pass or fail
Basic difference between American and Japanese 4 point system is points per difects. Japanese 4 point system was introduced earlier and this system contains some soft atitude for the seller. American 4 point system was introduced after the Japanese system and it is more strict than any other inspection system.

what is 10 point system in fabric inspectionIf you want to produce high quality garments, you need high quality piece goods. When a sewing factory receives fabric from the mill, it is difficult to conduct a full 100% inspection of the fabric. '''Apparel Search recommends a minimum 10% inspection of all piece goods prior to spreading the fabric. Many factories attempt to inspect the fabric during the spreading, but this is probably unrealistic to depend on the spreader to control the fabric quality evaluation. The fabric should be inspected prior to the fabric reaching the cutting tables. ''' There are several piece good inspection systems for measuring the quality of fabrics. Their is a Ten-Point System, which was developed in the 1950's. That system assigns penalty points to each defect, depending on the length of the defect. The system is a bit complicated because the points per length vary for warp and filling defects. There is also a Dallas System published in the 1970's. That system was developed specifically for knits. According to this system, if any defect was found on a finished garment the garment would then be termed a second. In regard to fabric, this system defines a second as "more then one defect per ten linear yards, calculated to the nearest ten yards." For example, one piece 60 yards long would be allowed to have six defects. Another system for evaluating piece goods is the Four-Point System. In this system, you should inspect at least 10 percent of the total rolls in the shipment. Make sure to select at least one roll or each color way. The defect classification works as follows.Size of Defect:3 inches or less = 1 point penaltyOver 3 inches but not over 6 inches = 2 point penaltyOver 6 inches but not over 9 inches = 3 point penaltyOver 9 inches = 4 point penaltyNote: a maximum of 4 points should be charged to one linear yard. Also, note that only "major" defects are charged.The acceptable score varies. Many companies use 40 points per 100 yards as acceptable defect rate. However, others may find this not acceptable...Here is some math to show you an example.Total Yardage received: 5400Acceptance Point-count: 40 per 100 yardsTotal Yards Inspected : 540Total penalty points found in the sample inspection: 150 points150 divided by 540 times 100 = 27.77 points per 100 yards (because the allowance is 40 points per 100 yards, this shipment would be acceptable).Above are only a few examples of fabric testing procedures. In fact, above is only a short summary of the processes. If you are responsible for inspecting fabric, you really will need to do more research on this subject

To calculate the electric field at a point in a given system, you can use the formula: Electric field (E) Force (F) / Charge (q). This formula helps determine the strength and direction of the electric field at a specific point in the system.
The formula for calculating the angular momentum about a point in a system is L r x p, where L is the angular momentum, r is the position vector from the point to the object, and p is the linear momentum of the object.
To calculate the formula of a reference point, you first need to determine the coordinates of the reference point. You can then use these coordinates to represent the point in terms of the general formula format, typically using variables like (x, y) or (x₁, y₁). This formula can then be used to calculate distances, slopes, or other relationships with other points in the coordinate system.

The transmission time formula is calculated by dividing the size of the data packet by the transmission rate of the communication system. This formula helps determine the time it takes for data to be sent from one point to another.
