Abstract
The experiment conducted was in order to find the relationship between the specific energy and the depth in an open channel flowing through an undershot weir, in order to understand the behavior of a flow at different depths, allowing for accurate engineering and designing of open channels. Depth measurements where taken at up-stream and down-stream for several weir openings in order to generate a specific flow open channel diagram, which will contribute to the analysis of open flow channels.
In many cases the major features can be expressed in terms of only a few variables, whose behavior can be described adequately by a simple theory. The principal forces at work are those of inertia, gravity and viscosity, each of which plays an important role.
The flow rate was constant throughout the experiment at 4.98 l/s, and values for Ec and yc where calculated at 0. 04560 and 0.03040 respectively.

    The first limitation encountered was during the river planning; the tape at the baseline was broken and so measurements began at 3m. This meant that 3m had to be taken off the results gathered so that they were accurate. Another major limitation was the presence of large boulders further upstream when the velocity readings were taken. Although there were no rocks in the area of water being worked on, there were large boulders just upstream which almost completely stopped the flow of water. This meant our results appear incorrect as the water was moving very slowly in an area where it should have been moving…

    Bridge), (2) the largest poo, (3) a quickest riffle, and (4) the smooth cement outflow at the west end of the park. Each group was assigned one of the sites. The first task required each group to measure out 5m at the assigned site with a tape measure and mark off the boundaries with flags. Then the group measured the velocity of the stream at that site by placing a bottle in the center of the stream and timing, with a stopwatch, how long it took for the bottle to go 5m. Repeat this three times. Next up was finding the discharge. The group marked off 6 different points within the 5m boundary in 1m increments. The depth was measure at each of these 1m increments at a width of ¼,1/2, and ¾ the distance from one side of the stream to the other. The group summed the discharges for each 1m section to obtain the total stream discharge. Next the group found the pH of the water by using the Vernier LabQuest and pH probe. The stream water temperature was calculated next. In order to take the temperature, the Vernier LabQuest and temperature probe were used. The temperature was taken at the surface of the stream and 1cm from the bottom. Dissolved oxygen was then found with the DO Chemets Kit. The group repeated this 3 times. A sample of lotic water was taken as well as benthic organisms. When the group returned from lab the Nitrogen and Phosphorous…

    Pipe 2 had a length of 2.51 feet and a diameter of 1.06 centimeters. Average results can be found below in Table 4. This diameter decreased the observed time to 139.9 seconds. Once again as there was more head loss the time increased per interval and the Reynolds number decreased. As shown in Figure 5 below the theoretical efflux time for pipe 2 was slightly less than the observed time at each interval. The percent error was also greater (< 11%), making the data less accurate.…

    Also you can get a better overview of the general trends in a rivers processes and landforms over its full course. We can be more certain of our conclusions about the pattern along the Holford Combe River and how closely they relate to the Bradshaw Model (fig 1). The length is very important because we were only aloud two days outside of school lessons to complete the data collection. The being short meant we were able to walk the length of the river from source to mouth and not waste time from travelling to different sites. It’s a good site choice from a health and safety perspective (fig 6) as the river is not to wide or deep and being short as well. Also erosional processes haven’t had much time to act against the river channel, to make sure it didn’t make it dangerously deep or wide. The river was very accessible to us from school (only 47 miles, South west of Bristol), so it was very easy to get to and realistic and cost effective for the site…

    The Flow-Measuring Apparatus is designed to accustom students to typical methods of measuring the discharge of an essentially incompressible fluid, whilst at the same time giving applications of the Steady-Flow Energy Equation (Bernoulli's Equation). The discharge is determined using a venturi meter, an orifice plate meter and a rotameter. Head losses associated with each meter are determined and compared as well as those arising in a rapid enlargement and a 90-degree elbow. The unit is designed for use with the TecQuipment HI Hydraulic Bench, which provides the necessary liquid service and gravimetric evaluation of flow rate.…
