Calculation Of Specific Gravity

Image
 Calculation Of Specific Gravity:- The Specific Gravity (it is also written as sp.gr.) of a substance is the ratio of the weight of a given volume of the substance to the weight of an equal volume of some standard substance (which is taken as water at 4degreeC) Obviously it is a pure number and processes no dimensions. Hence the Specific gravity of a substance =(the weight of volume   v    of the substance)/(the weight of volume    v   of the standard substance) =(the weight of a unit volume of the substance)/(the weight of a unit volume of the standard substance) =(the mass of a unit volume of the substance)/(the mass of a unit volume of the standard substance)      (as weight=mass*g) =(the density of the substance)/(the density of standard substance) This is the final step for Specific Gravity.   True specific gravity can be expressed mathematically as: where is the density of the sample and is the density of water. The apparent specif

Number Relation in table 9 for Primary Students

In mathematics, a multiplication table (sometimes, less formally, a times table ) is a mathematical table used to define a multiplication operation for an algebraic system. Visual representation of the different multiplication tables from 2 to 50 The decimal multiplication table was traditionally taught as an essential part of elementary arithmetic around the world, as it lays the foundation for arithmetic operations with base-ten numbers. Many educators believe it is necessary to memorize the table up 9 multiply by 9.  Number Relation in table 9 :- There is a relation between the digits of all numbers in Multiplication Table of 9 Please see this relation; 9*1=09    where    0+9=9 9*2=18     where    1+8=9 9*3=27     where     2+7=9 9*4=36     where    3+6=9 9*5=45     where     4+5=9 9*6=54     where    5+4=9 9*7=63      where    6+3=9 9*8=72      where    7+2=9 9*9=81      where    8+1=9 9*10=90    where    9+0=9 It proves that

Fluid Pressure

Pressure at any point of a fluid. :-  Pressure is the amount of force acting per unit area. The symbol of pressure is p or P     Mathematically: where: is the pressure, is the normal force, is the area of the surface on contact. Pressure is a scalar quantity. It relates the vector surface element (a vector normal to the surface) with the normal force acting on it. The pressure is the scalar proportionality constant that relates the two normal vectors: Uniform Pressure :-     The pressure on a Plane area is uniform when the thrust on any portion of it is proportional to the area of that portion, and the pressure is measured by the thrust on a unit area. Mean Pressure :-  The mean pressure on a plane area is the uniform pressure on it which will give the same resultant thrust as the actual one. Pressure at a Point :-  The Pressure at any point of an area is the limit of the mean pressure on an indefinitely small area enclosing the point.
