The Hydrostatics Pressure is either utilised in the working of a Hydraulic Structure,or a Structure is checked to withstand the Hydrostatic Pressure exerted on it.That's why study of Hydrostatics is more important .In this post I will cover practical applications of Hydrostatics on the following Structures.
01)Water Presure on Sluice Gate:-
To regulate the flow of Water,in the path of a River,a Sluice Gate is provided.The Sluice Gate is made to move up and down with the help of Rollers fixed on Skin Plate,which travel on Vertical Rails called Guide.
These Rails are fixed on Piers or Vertical Walls.In between these two Skin Plates,a number of I-beams are provided horizontally to withstand the Water
Presure.The spacing between the I-beam is lesser at the bottom than that at top of Sluice Gate,as the Water Pressure varies in the depth.
02)Water Presure on Lock Gate:-
The Water Level on both sides of the Dam will be different.If it is desired to have Boating in such river,the Chember,known as Lock,is constructed between
these two different Water Levels.Two sets of Lock Gates are provided in order to transfer a Boat from Higher Water Level to Lower Water Level.
The Upstream gates are opened,and the Water Level in the Chember is rises up to the Upstream Water level.The Boat is then shifted in the chember,then
Upstream Gates are closed and Downstream Gates are opened and the Water Level in the Chember is lowered to the Downstream Water level.
The procedure is reversed for the transfer of Boat from Downstream to Upstream.
03)Water Pressure on Mansory Walls:-
When Water on one side of Mansory Walls,the Water Pressure will act perpendicular to the Wall.A little consideration will show,that the intensity of Pressure at Water Level will be Zero and will be increase by a Straight Line Law to wH at the bottom.
Thus the Pressure of the Water on a Verticle Wall will act through a point at a distance H/3 from the bottom,where H is the depth of Water.
Conditions for Stability of Dam.
01)The Resultant must pass within the base to safeguard Dam against Overturning.
02)The Resultant must pass through the middle third of the base,to avoid tension at the base.
03)To prevent sliding,the maximum Frictional Force should be more than the Horizontal Force.
04)The Maximum Stress developed at the bottom of the Dam should be within the permissible Stress of the site.
