The term “permeability of soil” refers to the capacity of soil to allow the passage of liquids such as water. For buildings that will be in contact with water, this is a crucial consideration. A soil’s empty areas are linked together, allowing water to move through them.?
Water flows in a meandering course rather than a direct one. But in soil mechanics, the assumed flow direction and effective velocity are both straight lines. When pores are larger, flow rates are higher

HOW TO SELECT THE RIGHT SCHOOL FURNITURE ?
School Furnitureplays a very critical role in a child’s learning process. The make, size and dimension and the orientation of the right kind of furniture providesa certain mood and ambience to the classroom and can greatly influence the students’ comfort and behavior. For instance,proper seating arrangement with proper furniture results in informative communicationas perfect layout encourages better interaction between students and teachers.
Design and Elasticity:The design and elasticity of the furniture must be aligned to the modern classroom teaching strategies and multi-grade teaching. Therefore, compromising on quality can lead to discomfort. As newer and better learning systems emerge, with classrooms becoming more and more dynamic, furniture needs to reciprocate accordingly. It should be easily reconfigured to support the required group sizes, enabling better communication and flexibility.
Ergonomics:It is now a proven fact that comfort leads to better learning. School furniture should be ergonomically sound, providing better relaxation to back muscles and shoulders, provided that students are required to sit in those chairs for the major part of the day. The furniture should be designed in a way that it supports body’s natural inclination to shift and change postures easily.
Safety:One of the primary factors to consider when buying school furniture is the element of safety. The furniture should be child-friendly with no sharp edges and corners. They should be made with environment friendly material, should be coated with non-toxic paint etc. Care should be taken to see that no nails are jutting out from any corner to prevent accidents. A combination of great outdoor and indoor spaces in a school is what accounts for a safe and friendly atmosphere and a good selection of furniture is definitely the first step in that direction.

What are the differences between permittivity and permeability?
Two of the most complex and least understood constants in Physics are the Permittivity and Permeability constants. It's always fun watching people try to explain these two. Just what are these constants? How do they affect the bigger picture?
Let's stop that line of thought for a minute. We're going to diverge to a physics topic that may seem to be off course (or is it?). Going back to elementary Physics, the Newton-Laplace equation.
Speed of Sound
c=pρ??√?=??
c? is the speed of sound p? is pressure ρ? is density
The Newton-Laplace Equation & Speed of Sound
In order to determine the speed?of sound in a particular medium, we need to know the medium’s elastic properties and its density. A medium’s elastic properties determine whether or not the medium will deform or lose its shape due to external forces. Sound travels faster in mediums with high elasticity and minimal deformity – like steel. Sound travels more slowly in less rigid mediums that deform easily – like rubber. Sound travels more slowly in mediums with greater?density.
Sir Isaac Newton proposed a simple formula for calculating the speed?of sound. Years later Pierre-Simon Laplace would revise Newton’s formula and the new formula would be called the Newton-Laplace Equation.
