Which of the following statements best describes conditions in turbulent flow?

A.   Fluid particles move along a smooth, straight path.
B.   Energy loss varies directly with the square of the velocity.
C.   Energy loss varies directly with the velocity.
D.   Reynolds number is always less than 2,000.

A Newtonian fluid flows through 2-in. commercial steel pipe (I.D. = 0.0525 m). 

Liquid Properties: 
Density = 1.00 g/mL
Viscosity = 1.05 cP 
Flow= 0.500 $$m^3//min$$

The Reynolds number is most nearly: 

A.   $1.93\times {10}^3$
B.   $7.94\times {10}^3$
C.   $1.93\times {10}^5$
D.   $1.15\times {10}^7$
