Hi,

Total pressure at the inlet is know as a freestream values but Total pressure at the outlet is not know before a computation is performed. To compute Total pressure at the outlet we also need to know the losess involved in the computaional domain, which will be know only after computation is know.

Comming to static pressure at the outlet is concerned, it gives more physical meaning as the flow needs to be relaxed to the back pressure at the outlet and hence given as exit pressure BC.

Please some one correct if I am wrong some where....

Thanks, Vinayender.
