Calculating Sumss Of Maths

Question

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?

Answer 1

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 $P=\frac12 P_{max}$
