Final thesis takes on a problem of measuring hydrostatic forces and the centre of
pressure on a submerged
at surface. The problem we were facing was to facilitate
measurements without the need for providing a sealing force, which would have an
impact on results. We have decided to construct and produce an acrylic vessel with a
circular "floating2 surface on which the force is measured in three points, by means of
which any rotation is prevented and it does not carry any sealing forces. The surface is
mounted on the vessel by a thin silicone membrane to reduce any losses due to internal
friction. Upon testing the device we have come to a conclusion that the forces deviate
from theoretical values for around 2.86-6.58%, and the centre of pressure around 0.43-8.12%.
