We know that;
Seepage,
Q=kH(Nf/Nd)
where,
k = coefficient of permeability of the soil
H = Total head loss through the soil
Nf = number of flow channels
Nd = number of equipotential drops.
Therefore, seepage quantity is proportional to both coefficients of permeability of the soil and total head loss through the soil.

Q = kiA.
i = h/l.
Hence,
Q directly proportional to k.
Q directly proportional to h.
i = h/l.
Hence,
Q directly proportional to k.
Q directly proportional to h.

Q = K*H*NF/ND.
NF = NO OF FLOW LINES.
ND = NO OF POTENTIAL DROP.
K = PERMEABILITY OF SOIL.
H = HEAD LOSS.
NF = NO OF FLOW LINES.
ND = NO OF POTENTIAL DROP.
K = PERMEABILITY OF SOIL.
H = HEAD LOSS.

V = KI.
K = Permeability of soil.
I = dh/dz = Potential gradient.
V = Velocity.
K = Permeability of soil.
I = dh/dz = Potential gradient.
V = Velocity.

Total head loss means (pressure, velocity, datum head) but in so in mechanics we are not considering velocity head than how it is true? Answer please.
Divya said:

@Maveen kumar. Since the velocity of water in soil is very less, we usually neglect velocity head in soil engineering problems.

I think the answer will be C.
Vinod kattimani said:

Option D is correct we are neglect velocity in problems only.

C is correct I think.

Option D is the right answer. I agree.
