Answer:
fluid pressure = 132590 pascal
Step-by-step explanation:
Fluid pressure can be calculated by using following relation:
![P_o - P_g = g\time p* (Z_b - Z_a )](https://img.qammunity.org/2020/formulas/chemistry/college/pdrgn48tja38ia79900zasf5nl1p3vcswy.png)
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
![\rho = density of fluid = 997 kg/m³](https://img.qammunity.org/2020/formulas/chemistry/college/a0vfxloz4gnfwam3vhmqlcqoaia4e3xoqt.png)
Z = location depth from surface of lake
Therefore ,
![Z_a = 0 meter](https://img.qammunity.org/2020/formulas/chemistry/college/uoqfkab1jmnx24ipw0t1ki9ff7ahsjgxz6.png)
![Z_b = 3.2 meter](https://img.qammunity.org/2020/formulas/chemistry/college/okorpoew34frnu7g64ctlc8pceruikhb08.png)
![P_b - P_a =g*\rhop* (Z_a - Z_b)](https://img.qammunity.org/2020/formulas/chemistry/college/cpdxyvm6ytb8jkygy5evxurogajypmafmb.png)
![= 31265 kg/m-sec^2](https://img.qammunity.org/2020/formulas/chemistry/college/tclkenzzrqliatlgnhvvftemq4433ecf8y.png)
1 Pascal = 1 Kg/(m.Sec)
![P_b = P_a +31265](https://img.qammunity.org/2020/formulas/chemistry/college/gxzkc4uk8rodm7r7fr7urc9mii6c6sfjd6.png)
= 101325 + 132590 Pascal
= 132590 pascal
