D. 5000
Explanation
Reynolds number (Re) determines the type of flow: Re < 2000 → Laminar flow 2000 < Re < 4000 → Transitional flow Re > 4000 - 5000 → Turbulent flow For most practical cases, turbulence begins around Re = 5000 .

B. The functions f(x) and g(x) be derivable in (a, b)
C. None of these
D. The functions, f(x) and g(x) be continous in [a,b]
Explanation
Cauchy's Mean Value Theorem states that if two functions f(x) and g(x) are continuous on the closed interval [a, b] and differentiable on the open interval (a, b), and g'(x) ≠ 0 for any x in (a, b), then there exists a point c in (a, b) such that: (f'(c) / g'(c)) = (f(b) - f(a)) / (g(b) - g(a))
The necessary conditions for Cauchy's Mean Value Theorem are :
1. The functions f(x) and g(x) are continuous on [a, b]. 2. The functions f(x) and g(x) are differentiable on (a, b). 3. g'(x) ≠ 0 for any x in (a, b).
