Solved: Develop a general-purpose computer application (using EES or other software)

Chapter 14, Problem 14-153

(choose chapter or problem)

Develop a general-purpose computer application (using EES or other software) that employs the affinity laws to design a new pump (B) that is dynamically similar to a given pump (A). The inputs for pump A are diameter, net head, capacity, density, rotational speed, and pump efficiency. The inputs for pump B are density (rB may differ from rA), desired net head, and desired capacity. The outputs for pump B are diameter, rotational speed, and required shaft power. Test your program using the following inputs: DA 5 5.0 cm, HA 5 120 cm, V . A 5 400 cm3 /s, rA 5 998.0 kg/m3 , n . A 5 1725 rpm, hpump, A 5 81 percent, rB 5 1226 kg/m3 , HB 5 450 cm, and V . B 5 2400 cm3 /s. Verify your results manually
