Calculation of the coverage area:
X = K
* D
iameter of N
ozzle * V
elocity of Air stream at Outlet/Velocity at Throw point
{K = C
onstant (5.0)}
X = 5 * 0.18 * 16/0.7 ⇒
X = 20.5 M
Now, In the above Triangle,
Tan 12° = Y
1 / X
⇒ Y
= X
Tan 12°
⇒ Y
= 20.5 Tan 12 ° ⇒
Y = 20.5 * 0.21 ⇒
Y = 4.31 ≅ 5
Generally w
e assume X
= 25, Therefore coverage area = 2* {25*6}= 2*150 = 300 Sq M
