Reflection Report #2:Using a 1/12th scaled down PVC pipe model, the team discovered that the wall-thickness of the pipe was causing backwards flow out of the port. To overcome this obstacle, two new models were made using thin copper piping. These two models were used to perform an experiment of capturing the flow out of the 1st and 15th ports. Additionally, the team continued to modify the experimental set-up to create a flow rate that was both quiescent and large enough to produce the desired head loss.
Reflection Report #3: Experiments were The team modified the experimental set-up so that experiments could be conducted on both a submerged pipe and a pipe suspended in the air. Repeated flow Flow collection experiments on the latter showed that the flow from the last port is consistently higher than that of the first port, indicating pressure recovery at the last port. Dye tests on the submerged pipe clearly indicate the presence of circular flow in the sedimentation tank. The higher concentration of dye at the end of the manifold proves that the water exits the orifices with a horizontal velocity. Our team is now researching on possible solutions to and dye test experiments proved that horizontal velocity and pressure recovery were indeed significant problems in the current inlet manifold design. Hence, our team is now researching for ways to solve these problems.
