hencethis prism must exert adownward pressure of 4gupon an area of 1 cm^ Butat the same depth the pres-sure in all directions is thesame, hence, generally, thepressure at any depth inwater may be taken approxi- ■mately as one gram persquare centimeter for eachcentimeter of depth (=c= 1,000 k per m^… … Fig. 110. METHODS OP CALCULATING LIQUID PKESSUEB. 149 any depth the water pressure at the given depth must bemultiplied by the specific density (p. 177) of the liquid. The conclusions arrived at may be summarized as follows:In a mass of liquid at rest, the pressure is the same at all pointsin any…
