Many people think that heat pumps dont work below 0 F. because there is no heat. Zero is actually -470 degrees or so below that, durn I should remember the correct number. Make personal note to learn it.........
We are immersed in the atmosphere so there is no pressure and more is pressure, less is vacuum. Right???
Well not really. Iam gonna get a GOOD gauge to monitor the pressure increase on the front of my car versus the static inside it. It is digital and should be of interest to this group.
Glad we have a thinking issue now and then to keep the cobwebs to a minimum. ENJOY W

True words Woody. I will be running tubing from the front of the car to the cabin. The cabin should give me ambient or close to ambient air pressure. This will be my "stagnant" value. I will measure in front of the grill and behind the grill to see any differencial.
I will not likely be able to tell how many Lbs or inches of water the ram pressure will provide the TB but I will be able to prove that ram air has dynamic pressure and whether it is a different value in front of the grill than behind.
One note on the grill popping out. It is likely that the airflow over the grill caused the lower pressure in front. Seems counter intuitive but possible.
Gonna try my
"Myth Busters" episode this coming weekend.
Querry?
What is a good way to get tubing inside the cabin without opening a window?
