Intern Experiments - 4

sorry for not been able to write for long... we have done a lot of experiments since then.... i will try to give you a feel of it...
we have identified the two main culprits behind the vacuum formation...( vacuum is something which we call it here . .. it is actually pressure falling below atm pressure .. so in that case its a kind of vacuum)
one it is the slamming of the door .. which we cant do without.... and the other is the starting of the fan soon after the slamming...we tried to seperate the effects due to the two.. we considered the delay of the fan motion after the door slamming...
the pressures come back to normal after a span of approx 30 s.. so we delayed the fan motion for 30 s.. so as two identify the two factors seperately...
the results were very conclusive and the pressure was reduced considerably.. the fan and the slamming together produce higher vacuum than the two separted effects... the peak occured on slamming..
these experiments were conducted in a kind of raw manner... then these experiments were conducted more precisely and acuurately in the performance lab, where the temp and humidity of the chamber is maintained at constant.
we then conducted our experiments there to confirm our findings...

after this we started a new set of experiments about which will i write soon...
