Second term neglect and l = 20.
So h2 = 2L.
h2 = 2*20.
h = 3.3m.
Near equal to 3m.
So h2 = 2L.
h2 = 2*20.
h = 3.3m.
Near equal to 3m.

ASSUMING L=100m then ,Cs=(400/(2*100))+(8000/(8*100^3)= 2.001m.
Which less than 3m.
Which less than 3m.

l = 20 m.
H2 = 2l,
H2 = 2*20,
H2 = 40.
And;
H = 6.32 or 6.33,
√40 = 6.32.
H2 = 2l,
H2 = 2*20,
H2 = 40.
And;
H = 6.32 or 6.33,
√40 = 6.32.

Would you please explain the calculations! Why are you taken that h2/2l=1?

Second term will be neglected when h=3cm not 3meter for length 20 meter.

The question is wrong it should be h2/2l -h4/8l3 instead of h4/8l3.

h square = 40.
Square root of 40 = 6.32 or 6.33.
How get it 3.3?
Square root of 40 = 6.32 or 6.33.
How get it 3.3?

If h2 = 4O. Then h = 6.324.
How it will come 3.3? Please explain.
How it will come 3.3? Please explain.
