Which of the following quantities are computed by using the hydraulic radius for noncircular ducts ?
Correct answer: D. Reynold number, relative roughness and head loss
- A. Velocity and relative roughness
- B. Head loss and velocity
- C. Reynolds number and friction factor
- D. Reynold number, relative roughness and head loss
Explanation
For a noncircular duct, the hydraulic radius gives the equivalent diameter, D_e = 4R_h. This equivalent diameter is used in Reynolds number, relative roughness, and frictional head-loss calculations.
