Question

Design and Selection of a Pump-Piping System
A project requires a pump that will operate with a minimum discharge of 20 L/s
against an elevation head of 40 m. The distance between the supply and delivery
points is 150 m. A ball check valve will be used in the system that consists of
commercial steel pipes. In order to produce a solution that meets the specified needs
for the system design, it is required to determine the most economical pipe diameter
for the pipeline and select a single pump from the figures below (including its
operating conditions) if the total cost (in thousands of dollars) can be expressed as
C = d175 + 0.75P + 18
where d is the pipe diameter (cm] and P is the pump power input [hp].
The followings are required to be conducted:
1. Describe clearly the mathematical model (equations/formulac) used to
conduct the system design.
2. Design the pump-piping system (pipeline size, pump selection and total cost)
using one of the modern engineering software.
3. Analyze and discuss the different possible designs, and use engineering
judgment to draw conclusions.
4. Professional and ethical responsibilities have to be considered (e.g.
appropriate referencing).

Three pumps are connected in parallel. According to pump performance curves, the shut off head of each pump is as follows: Pump 1: 7 m, If the net head for this pump system is 8 m, which pump(s) should be shut off? Pump 2: 10 m, Pump 3: 15 m Pump 1 O Pump 2 O Pump 3 O Pump 1&2 Pump 2&3
While planning a future expansion, a water distribution pipe will be replaced as shown in Figure 2. The current plan is for the new configuration to have the same head-loss between points A and B once the new pipes are laid. Considering that the physical characteristics of these new pipes will be identical to the previously laid pipe (L, D, CHW), (A) what will the new operational flow be? After years of wear and tear while operating above the required flow, the pipes have prematurely degraded. The Hazen-Williams coefficients have dropped to: CHW₁= 130, CHW2= 135, CHW3= 125.
