I used to lecture in Building Physics, specialising in the flow of solid-liquid mixtures for the paint and plastics industries. When we were looking for someone to vet the Tesco noise predictions for the gravel pipeline, I seemed to be the best available candidate.
If we were wrong, and there is a slurry transport specialist out there, please get in contact. Failing such a resource, I had to look at the situation myself. Not being a specialist, it took me some weeks to read up on the subject and analyse the Tesco consultant's report; but I am now fairly sure that . . .
. . the Tesco prediction for noise from our pipeline is a gross under-estimate.
How so ? Well, basically, slurry flow through a pipe and the noise it makes is impossible to predict from theory and has to be measured from an actual pipeline. The Tesco consultants have tested one, but it is a different, much less noisy system than the one we are getting in Seaton.
I have compiled the details into a paper (with references) which I shall be sending on to the Environmental Health Officer in EDDC, as well as to the planning people. I have seen two letters of objection to EDDC from Trevelyan Road residents which are not aware of the true noise situation; and I shall send a copy to them as well. I am happy to send it to anyone else who wants to see it.
However, I exclude Tesco consultants. Do your own work.
