Therefore, fineness modulus of aggregate = (cumulative % retained) / 100 = (275/100) = 2.75 Fineness modulus of fine aggregate is 2.75. It means the average value of aggregate is in between the 2 nd sieve and 3 rd sieve. It means the average aggregate size is in between 0.3mm to 0.6mm as shown in below figure.
The particle size of course sand ranges from 2 - 4.75mm, Medium sand ranges from 0.425 - 2 mm and fine sand ranges from 0.075 - 0.425 mm. The bigger particle size of the sand gives wet or dry sandy soil a grainy texture when you rub it between your fingers, and it makes the soil light and crumbly even when you try to stick it together in your hand.
Factors other than wave energy also determine sand grain size at a beach. The size of sand grains is related to the slope of the beach. For example, the steeper the beach, the larger the sand grain size tends to be. This is because larger particles can be cast higher up the beach by the waves on steep beaches.

When you compress a digital file, you remove bits of information in order to reduce its overall size. There are two types of compression: lossless, which reduces the file size without reducing quality, and lossy, which reduces the size and quality. Because of the nature of JPEG files, only lossy compression is possible with these kinds of images.
