Further research: After a semester of experimentation, the team has identified the appropriate direction in which to proceed. It is now clear that the new ram pump should take on a more compact form, in which all components (waste valve, check valve, air chamber) should be all closer and more directly connected to one another. The team has created a new preliminary setup, taking into account the aforementioned considerations. In the first run the new setup demonstrated impressive results suggesting that the recommended path proved to be correct. However, further documentation of the setup is needed since barely one trial was taken. Of course the setup can be continued to be improved by implementing more of the outlined considerations, such as the dual tubing in the air chamber or properly securing all components, but in no way limited to these.
To kick off the fall semester of 2016, the team will work with the model that was refined last semester and develop an efficient method of calculating the flow rate of system. To do this, the Bernoulli principle of incompressible fluids, as well as the Ideal Gas Law, will be applied with the data obtained and then compared with the previous method (effluent receptacle and timer). The team hopes this will allow smoother collection of data moving forward with the project. Furthermore, the team wishes to observe the effects on the pump once distribution piping is added to the waste valve. Addition of the elbow may have have adverse effects such as unintended vacuums and other complications. Lastly, a more compact and secure ramp pump with respect to its components is a goal for the team. With this in place, the union collar design may be modeled using AutoCAD.
