Pulling Vacuum through Manometer
Pulling Vacuum through Manometer
(OP)
Hello,
I am referencing my old Thermo book, but seems I am missing something.
I want to pull vacuum on water in a basic manometer which is of square construction out of stainless steel. One side is open to atmosphere, A1 and P1.
Am I wrong for thinking the ratio of A1 to A2 will have an affect on how it acts? In other words, if A2 on the vacuum side is 3 times larger than A1, for every inch of water I pull on A2, A1 will drop 3 inches?
I am trying to figure the size of my manometer and the ratio of A1 to A2 so I can pull about 25 inches of water.
Any equations or input would be awesome. Thanks.
