Experimental rig - Article Example The water flow duct is rectangular in shape and has the size 3500mm long by 1000mm wide and a depth of 1500 mm with a tank that has a capacity of 70 liters. The closed loop system is designed to hold water and the rectangular supply tank is connected to a centrifugal pump. Water is pumped by the centrifugal pump, from the supply tank, into the PVC pipes with 2 inches size, then through the transparent channel and into the supply tank again. The centrifugal pump is a two stage self-priming type and it has the capability to drive the water from the tank. The rectangular channel of the experimental rig has been designed and fabricated in such a manner that there are four transparent polycarbonate plates with dimensions ( which have been used to fabricate the channel. Acrylic was selected for fabrication of all sections of the channel, due to strength and transparency in addition to acrylic welding are soften the plate surfaces so they merge, and the molecules between the two pieces become one which gave much more strength to the channel and prevent leakages. Four pressure tabs are placed at the bottom surface of the channel used for the measurement of pressure drop. These tabs made the test sections where placed after two sections of in order to get full turbulence flow. The pressure drop of the rig has been taken for section. The experimental rig has a flow duct made from 2’’ PVC piping across the system. It has a plate cover that is 120 mm wide by 120mm height by 2000 mm long. This cover plate is made from polycarbonate material. The flow duct also has six 2’’ ball valves that are strategically located at the points of entry and exit of the water and are primarily to regulate the flow of water. The rig system is supplied with 240 volts of alternating current and in this regard, the experimental rig has 2’’ female sockets.
