Hi Ian,
The Bosch Automotive HB has something basic on calculating them, Fd=A+Bv+Cv^2. You could do a little equation solving Coast down 80 to 60 time and 30 to 20, two equation, three unknowns. I would set aero to zero at low speed and substitute that into high velocity. You'll have a lot of...
Hi Lcubed,
Something else to consider, seems to me that the pressure regulator is build into the pump meaning the spill never made it to the screw-on filter and it was a partial flow of the pump. The particular one I last had apart any way.

Hi russell9990,
HP Instruments had a series of application notes I found very useful to get started, but it was 13 years ago (paper) if you can find them. They are very hands on.

Hi par1, order is how NVH folks track and relate vibration/noise to rotating machinery thorough different rotational speeds. For a 6 cylinder 4 stroke @600 rpm, (600/60)= 10Hz, exhaust firing frequency tracted at same conditions lines up with 30Hz (600/60)*3 or 3rd order (30Hz). A lifter tick...
