During the week Sunday
28th June to Friday 3rd July 1998, we took part in the Northeast Industry
and Schools project week based at St Hild and Bede College Durham.
Our project was supplied by Glaxo Wellcome engineering department at Barnard
Castle. The project was to investigate the flow rate of plate orifices.
These are plates with a hole to control fluid flow in pipes. We were
given a simple mathematical model of the flow and apparatus
to control the flow. The aim was to determine the suitability of this model
for different shapes of orifice plates. The plates have
differening upstream/downstream profiles or a different diameters. We found
that increasing the diameter of the orifice or the head of water increases
the flow rate. We found that if the shape of the downstream face
of the plate was changed the flow rate was also changed, but if the shape
of the downstream face is changed then there is no corresponding change
in flow rate. The model involved some interesting extensions
of A-level physics work; applying Bernoulli's and Torricelli's equations
and understanding laminar and turbulent flow. This project involved
a real engineering problem and gave us a taste of what an engineering degree
could involve.
After the week we
wrote a report on our findings and for this received the Gold
Crest Award
After Sixth Form,
Robert will study engineering at Cambridge University.
