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 Cd1.75 +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/formulae) 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).
