An ideal fluid,of density 0.85 ´ 10³ kg/m³,flows at 0.25 kg/s through a pipe of radius 0.010 m.What is the fluid speed? A)0.85 m/s B)1.3 m/s C)3.0 m/s D)0.94 m/s

Question

Quizplus · Accepted Answer

The correct answer is D because the fluid speed is given by the equation v = Q/(πr^2), where Q is the flow rate, r is the radius of the pipe, and π is the mathematical constant pi. Plugging in the given values, we get v = 0.25 kg/s / (π(0.010 m)^2) = 0.94 m/s.
