Formula to be used: Where: Please take note! Calculating Pressure in a Static Fluid or P = pgh or P = yh p is the fluid's density (kg/m³ or lbm/ft³) g is the acceleration due to gravity y is the specific weight of the fluid (N/m³ or lbf/ft³) W is the weight of the fluid (N or lbf) A is the area of the bottom of the vessel containing the liquid (m² or ft²) h is the depth/height of the fluid (m or ft) P = P = 1248 h that will be used for the formula may be different from the given height of liquid in a problem. Refer to the sample problem below for clarification on this matter. Sample Problem For the dam shown on the right, find the pressure at point 20 feet below the surface of the water. Solution: Here, we will not use h = 40 ft since we are asked to compute the pressure at point 20 feet below the surface of the water. So, here is the appropriate approach to this problem.

QV: a hydraulic press is used to compact powdered samples. The device is made of two interconnected cylindrical chambers filled with oil if density psubscripto anc closed by two pistons. The small chamber on the right has diameter d and the large chamber on the left has diameter 5d. A lever is attached to the piston pushing down on the fluid in the small cylinder. The horizontal lever is hinged on the left, at distance L from the small piston, and a force of magnitude Fsubscript0 is applied vertically down at distance 2L from the hinge (Fig.5). You may assume that the lever and pistons have negligible mass. a. Determine the magnitude of the force Fin that the small piston exerts on the fluid in the small cylinder. Hint: you may consider that the lever is at rest in the horizontal position. b. Determine the pressure change applied to the fluid by the small piston. c. Determine the magnitude Fout of the force that the fluid applies to the large piston.
