Use a rope to measure the depth from the surface of water in the well to the platform of the well. Fold the rope in half and drop it to the surface of water, the part of rope that exceeds the platform is 9 m; fold the rope three times and drop it to the surface of water, the...
The present invention relates to a double fishing float capable of easily measuring the depth of water and controlling buoyancy minutely, wherein the double fishing float (100) comprises: a float top part (11) of a rod float (10); a body part (12) provided at a lower portion of the fl...
Measure the depth of the water from the top of the stake. Once the width and depth of the water are known, a weir table is used to compute the flow. The weir table shown here is based on a gate that is 1 inch (25 mm) wide. Simply multiply the table amount by the width (in ...
