Problem: A 6 inch gate valve with a flow coefficient 150 permits 500 gpm of oil with a specific gravity of 0.88 to flow through a piping system.
Approach: So pop quiz, can you remember from a couple of problems ago what was the search term that you needed to find the formula that has to do with this flow...
Key step: So that's 500 over the CV, which is given as 150, that quantity squared and that's multiplied by the specific gravity, which is 0.88.
Result: And that equals 9.8 psi, the best answer choice is C.
