+ pascal's Law and Fluid Static Law. - pascals Law o pascals law stats that the pressure intensity at a point in a fluid at rest is the same in all Directions. Consider a small prism of fluid of unit thickness in the z Directon contained in the Bull of the fluid. Since the crogs sectiond Alla of the prism is equilateral Trungle, Ps is t angle of 45° with x-axis. if the pressure intensities Normal to the three surfaces are p_1,p_2,p_3 Force = preSSure XAlla Force on Face: AB = P, x (ABXI) BC = P2 X (BC XI) AC = 13 X (ACx1), - Fluid Static Law? The fluid static law states that the pressure in a fluid increases with increasing depth. In the case of water this is termed the hydro static low. consider a vertical Column, height h (m). of fluid of constant cross sectched Aren Alm's totally sarounded by the same thid of Density p (kg/m^3) for vertical equillibrium of forces. Force on base = weight of Column df Fluid weight of Column = = mass x accelaation due to graut, w= m. 9 The Mass of fluid Column = its density x Volume The volume of the column = Area of the base? The weight of Column: PXAXHX9 Force = pressure xArla PXA = PA.h.9 P = Pxg xh.
