Accurately calculating the pressure drop through an orifice

I have a scenario where a specific nozzle is defined to have a flow of 900cc/min.
The flow co-efficient for this nozle is defined @9.8 MPa -> flow co-efficient= 0.85.

If I then run fluid through this nozzle at say 200 MPa and I would like to calculate the pressure drop.
My understanding is taht I would not get an accurate answer using the flow co-efficient of 0.85 as this is valid at 9.8 MPa.

Therefore how can I calculate the pressure drop?
