Design For Manufacturing and Integrated Manufacturing Systems Assignment -

Water is pumped at the rate of 14 m³/min through a centrifugal pump (Figure 1) operating at a speed of 1750 rpm. The impeller has a uniform blade outlet width, b, of 50 mm with r₁ = 50 mm and r₂= 175 mm, and the exit blade angle is β₂= 23^o (Figure 2). Assume ideal flow conditions and that the tangential velocity component, V_θ1, of the water entering the blade is zero (α₁ = 90^o). The major steps/stages which this project should follow are detailed below:

1. Material selection for the components (impeller) is normally done by the Design Engineering team. However, you need to propose and justify suitable specific materials for the components of the impeller. The materials must be good from both the design and manufacturing point of view.

2. Recommend and justify a production method (batch production or mass production) for the component of this impeller.

3. Determine: (a) the tangential velocity component, V_θ2, at the exit, (b) the ideal head rise, h_i, and (c) the power W^-_shaft, transferred to the fluid. Discuss the difference between ideal and actual head rise.

4. Is the power, W^-_shaft, ideal or actual? Please give explanation.

5. How to design the pump with a 3D-software? Assuming the thickness of blade is 5 mm, please give an initial design and drawings.

6. To make a designed pump system which is visible.

Note - For assignment, the flow rate of the pump is 14m³/min not 14 kg/min. Please use 14m³/min to work out the number of blades (impeller).
