dear colleagues
in the sizing of the restriction orifice vendor said that
due to high deferential pressure through the orifice we have chock flow
this RO has been installed after the BDV.
AS i think chock flow dos not have any problem for us on operation is not it?
he suggest to use the multi stage type of RO
my question are:
does it have any problem for us if the flow will chock
why the vendor said that he want to use the multi stage ,.
i think vendor wanted to reduce the noise due to this high pressure i think .it is reasonable to use the multi stage
but what about the chock flow
dos it need to prevent from chock flow
thanks
mike
