Problem: Fluids 18, crude oil is pumped by a centrifugal pump with a performance curve given by the equation, had equals 50 minus volume flow rate minus vol...
Given: 000 in 25; 8550 GPM; 16.43 feet
Approach: So first of all, let's think about these two functions, and we'll have to remember a little bit of math here, not too much, jus...
Key formula: equation is Q is going to equal negative B plus our minus the discriminant
Calc: So HP equals HS, let's do our substitution 50 minus Q minus Q squared over 25 equals Q squared over 25 plus Q over 10.
Calc: And now let's get everything on one side equal to 0.
Result: And we get a final answer of 30.5 horsepower, which is closest to answer choice be.
