Sorry, yes it was a typo it is 7 psi permanant pressure drop.
And I have done the enthalphy calc, and i didnt see any real temperature lose till far higher pressure losses.
Thanks all for confirming...
My Orifice plate calculator gives me my permanant pressure loss, but on superheated steam do I get a temperature change.
For example 750 psi 750 F steam, I require a DP across my orifice of about 500" water to get turndown and Beta ratio. ( yes I know its high but pipe dia fixed.)

Discounting the duct velocity, is there an upper air intake velocity for outside air intakes that should be avoided.
I have heard very low numbers to reduce the possiblity of the intake collecting leaves or dragging in rain snow?
Also would intake angle:- vertical,inclined 45 facing down and...
