How to solve?

dw = sgd[Fc- PWP].
= 1.5x80x[0.25-0.15].
= 12.
= 1.5x80x[0.25-0.15].
= 12.

Explain dw, sgd, [Fc-PWP]?

Here, s = Specific gravity of soil,
d = Depth of root zone,
Fc = Field capacity,
PWP = Permanent wilting point.
d = Depth of root zone,
Fc = Field capacity,
PWP = Permanent wilting point.

@Mariya.
Here, dw means the depth of water zone. i.e., storage capacity of soil.

For formula is .....(Yd/Yw)*d*(field capacity-permanent welting point)
Given data:-
Yd=1.5,
Yw=1,
Depth zone=80 cm,
Field capacity=35%=35/100=0.35,
Permanent wilting point=15%=15/100=0.15,
So, (1.5/1)*80*(0.35-0.15)=12 cm,
Correct answer is 12 cm.
