System Comparison proof transient <-> steady state
 

Hi,

I have two similar systems I. and II.

I. is steady state and defined by these variables:
- Distance A
- Distance B
- Volume flow C
The resulting variable I am studying is T.

II. is transient and defined by these variables:
- Distance A
- Distance B
- Frequency f
- Pressure P
The resulting variable I am studying is T.

The literature I have read hints to the conclusion that II. may be expressed as I., which would save me a lot of computation time.

At the moment I am stuck with the following problem: How can I proof, that II. can be expressed as a modification of I. and how can I derive a set of equations, which describe the necessary modifications?

e.g.:

I thought about conducting DoE studies for I. and II. and using response surface methodology to find correlations. But I do not know if this would be either possible, or scientifically sound.

Any advice or ideas?

kind regards,
