Answer:
fluid pressure = 132590 pascal
Explanation:
Fluid pressure can be calculated by using following relation:
[tex]P_o - P_g = g\time p\times (Z_b - Z_a )[/tex]
Where
Pb = fluid pressure at a distance of 3.2 m below from surface
Pa = fluid pressure at surface = atmospheric pressure = 101325 Pascal
g = gravitational constant = 9.8 m/sec2
[tex]\rho = density of fluid = 997 kg/m³[/tex]
Z = location depth from surface of lake
Therefore , [tex]Z_a = 0 meter[/tex]
[tex]Z_b = 3.2 meter[/tex]
[tex]P_b - P_a =g\times\rhop\times (Z_a - Z_b)[/tex]
[tex]= 9.8 \times 997\times (3.2-0)[/tex]
[tex]= 31265 kg/m-sec^2 [/tex]
1 Pascal = 1 Kg/(m.Sec)
[tex]P_b = P_a +31265[/tex]
= 101325 + 132590 Pascal
= 132590 pascal
