Hello Sir,
I am trying to estimate the time required to empty a tank which has initial liquid level of H and an Orifice diameter of D but additionally a Flat plate kept at a distance d from orifice opening. Similar to an arrangement is shown in Figure.
I could not get clue on calculating the discharge coefficient for this restricted orifice due to the flat plate.
The flat plate is attached to a valve which is used for draining tank. This arrangement make the flow though, a kind of vertical ring section. Can I use the developed rectangular area as flow area for finding discharge?
Please give some reference on similar situation.
Thank you
