Considering the vertical motion of the liquid. Due to this difference of pressure an upward force will act on the ball and hence the ball will deviate from its usual path OA0 and will hit the ground at A1 following the path OA1 (figure shown) i.e., if a ball is thrown with back spin, the pitch will curve less sharply prolonging the flight. Normal atmospheric pressure at sea level (an average value) is 1.013 × 105 Pa. Thus the reading of the spring scale will increase by an amount equal to the weight of the liquid displaced, that is, by an amount equal to the buoyant force. When fluid in motion, if fluid particles preceding or succeeding a fluid particle follow the same path, then the path is called streamline and the motion of the fluid is called streamline motion. 10.GAS LAWS.
