Intern Experiments - 6

hii... so now the pull force experiment has starting showing result.. however it has not solved the problem fully. the door pull force if is around 4kgf then it can be considered ok.. but if one has to apply force higher than this its is considered to be a problem.we have drawn a correlation crudely btw the values of pressure and the corresponding force.
the force of 4kgf is shown when the pressure falls by .01psi below the atm pressure.hence we have fixed our aim to solve the problem by brining the force down to 4kgf in all the products.
we have been trying to reduce the force through vacuum valve and the fan delay .in some of the products this has proven to be sufficient , but in some products the force still is more than 4kgf. this is due to the variation in the different products of the the same model.
we then planned to carry out experiments as to where has been the differnce btw the products so that we can tackle the problem dually. we did the benchmarking of the two products which showed the two extreme of the results.however the benchmarking didnt gave us substantial results.
we then swapped the plenums of the two products so that the most important variable of the whole phenomena, fan can show us the difference when the plenum is replaced.
