![]() In this experiment, you will see several tanks, each with a hinged gate on the side. Watch this short video of the locks operating on the Panama Canal. The pressure on a submerged surface (in this case a gate) creates a distributed load, which can be considered to be an equivalent point load (single force) acting through the centre of pressure.īy converting the distributed load to an equivalent single force, and knowing the location where that force acts on the surface, you can determine the moment generated by the water pressure. In this experiment, you will combine your mechanics knowledge, with what you know about hydrostatic forces, to determine the moment generated by water pressure in three different tanks (bays) with rectangular, circular and triangular gates. Lock gates, such as this one from Blanchetown, South Australia, are an example of where it may be necessary to calculate such hydrostatic forces.īut how do you calculate such pressure measurements? If you need more help, please show us your work.The aim of this experiment is to demonstrate the principles of hydrostatic forces on submerged planes. Use the relationship \(\displaystyle F = P \times A\) to find the incremental force. column of water above \(\displaystyle y\), and What is the incremental Area (square feet) between \(\displaystyle y\) and \(\displaystyle y+dy\)?įind the pressure \(\displaystyle P(y)\) as the weight of a 1-sq.ft. \(\displaystyle y_2=8 \ln 18\) is the top.Īssuming also that the tank is full, we will find the total force by integrating the incremental Force \(\displaystyle y_1=0\) is the bottom, and ![]() ![]() ![]() IT IS NOT CLEAR WHICH IS THE TOP AND WHICH IS THE BOTTOM, but in the absence of that bit of information I will assume that One of the bounding surfaces is a vertical plane, and the boundaries of that surface are four curves or lines in the xy-plane.
