wet steam thru orifice 6

[sailoday28]

Sizing of orifice?
Reference thread124-139392

Why would engineers use a perfect gas formulation to determine flow rate of saturated steam (inital state) that will pass through an orifice?

I am not familiar with Napier's rule that applys in this context. Can you summarize please?

Yes, L'Hopitals first rule was for the indeterminant form 0/0, but his second rule applied to infinity/infinity.

Good luck,

I believe you will find it in the Stand Hand Book for Mechanical Engineers.

SEE EQ. 15
G=p/70
Where G =lbs/sec/sqin at throat,
p=stagnation press psia.
