Question 259158: This formula is supposed to be carburetor mm's open, and the resulting rpm's for peak performance with 2.8L displacement. Please advise on calculations of this formula:
D(p)=.75√(2.8)p
D=81
p=4166
If you would, please help with calculations to arrive at 4166, and I also need to reverse the formula where D=84, and p=4480. I'm not sure how to do this either.

Question 259287: Please help with an algebra application with carburetor open mm's and rpm's. I need to reverse this formula with the existing p=4480 and D=84 for the following, and instead of p=4480 as the result, need D=84 as the result.
Thank you very much!
D(p)=0.75√2.8p
D(p)=(3/4)(√14/5)p
D*2=(9/16)(14/5)p
p=(16/9)(5/14)D^2
p=(16/9)(5/14)(84)^2
p=4480
