Optimum economic pipe diameter for fluid is determined by the___________________?
Correct answer: A. Total cost considerations (pumping cost plus fixed cost of the pipe)
- A. Total cost considerations (pumping cost plus fixed cost of the pipe)
- B. Density of the fluid
- C. Viscosity of the fluid
- D. None of these
Explanation
The economic diameter minimizes total annual cost by balancing the pipe's fixed or installation cost against pumping cost. Fluid properties such as viscosity and density affect the calculation, but neither alone determines the optimum diameter.
