본문 The objective of this experiment is to determine the center position of pressure of a plane surface partially and totally immersed. We compare the experimental measurement with the theoretical prediction. 2. Background theory 1) Calculating of hydrostatic pressure We can assume that there is no shear stress and acting normal to surface. We write force equilibrium equation at X andZ axis. After calculating, we get the conclusion that pressure is only depend on the depth and increases linearly with depth in a fluid of constant density. sum _ ^ F _ x =F _ x1 -F _ x2 = (p- Partial p over Partial x dx over 2 )-(p+ Partial p over Partial x dx over 2 ) dz=0sum _ ^ F _ z =F _ z1 -F _ z2 -dW= (p- Partial p over Partial z dz over 2 )-(p+ Partial p over Partial z dz over 2 ) dx-dW=0 sum _ ^ F _ x` `:` Partial p over Partial x =0, sum _ ^ F _ z : Partial p over Partial z = rho g= gamma thereforeTRIANGLE p= gamma TRIANGLE z 2) Hydrostatic pressure on submerged plane With the equilibrium of torque equation, second moment of area and parallel axis theorem, we can calculate the z that is a position of the total force. The b that is the width of the plate doesnt influence on the z. When the submerged plate is close to the surface of the water(r=2d), Center of pressure is located on 1/3 point of the plate from the bottom.
