Knapen system of drying walls

Principle of  Knapen system : A difference of 16 °C to 24 °C is required to displace the vitiation air from a building by means of a vertical air shaft. The Knapen Tube : The method of fixing the Knapen tube in the wall. it is a simple porous tube which is fixed with its mouth inclined outwards. As the tubes are porous the moisture of penetrates inside them. Due to difference of temperature the dry air enters in the tube from its top portion as indicated by arrow. This dry air evaporates the moisture and saturated air comes out from the lower portion of the tube. This circulation of air is due to perfectly natural laws, and remains continuous till there is any moisture left in the wall.

Trigonometric formulas - Free Math Help

I always had trouble in calculating the angles because I did not remind the table that's why I had trouble in calculating the angle by the table. All my friends remembered the table but it was difficult to me to  pass the exam paper without angle, so I started harassing my teacher and asked him, "Sir, there is no other way or method  ." He helped me and make a  short trick with his help. That trick I tell you You have always used this table Another method  We can Calculate the angle by the left and right method .   As you know these are  some basic angle 0 °    30 °     45 °    60 °     90°  These are five angles that we get out of Eg sin30 °, sin45 ° etc Tan45 °, tan 90 °, tan30 ° etc. Cos0 ° cos30 ° etc  You just have to remember three formulas (L = left) (R = right) 1. SinΦ = √L / 4  2.cosΦ = √R / 4  3. TanΦ= √L / R  With example Suppose we have to find the value of sin30 ° Formula is   sin = √L / 4 Le
