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. P = yh The specific weight of water is 62.4 lbf/ft³. lbf P = (62.4 ft3) (20 ft) lbf ft² 40 ft 20 ftarrow_forward
