A vertical wall is subjected to a pressure due to one kind of liquid, on one of its sides. The total pressure on the wall per unit length is (where w = Specific weight of liquid and H = Height of liquid)
A. $${\text{wH}}$$
B. $$\frac{{{\text{wH}}}}{2}$$
C. $$\frac{{{\text{w}}{{\text{H}}^2}}}{2}$$
D. $$\frac{{{\text{w}}{{\text{H}}^2}}}{3}$$
Answer: Option C

P = Pressure;
P/h = Total pressure per unit length = integral((w*h)dh).
= (w*h^2)/2.
