Calculating Sumss Of Maths I need to work out the total thrust on a vertical wall. The 1st part of the question: Imagine a pool having dimensions of (x)m x (x)m and it has a depth of (x)m The density is $(x)kg/m^3$ pmax + pmin / 2 pa x area will then equal the total thrust?

Yes your evaluation is correct but to be more precise we have to distinguish between

* maximum pressure $P_{max} = 1024 \cdot 9.81 \cdot 1.5$



and

* mean pressure $P=\frac12 P_{max}$
