Derive an expression for pressure exerted by a liquid column and discuss the different factors affecting the pressure at a point. |
|
Answer» ression for the pressure is hpgLet the liquid column of area be = A (GIVEN)LET the height of the container be = h (Given)Let the pressure at upper and lower columb of the liquid be = P1 and P2Volume V = A h,Where its mass when DENSITY of the liquid is ρ is represented by,mass = m =Ahρ and the weight acting VERTICALLY downwards is represented as W = AhρgNet pressure acting downwards = P1 + w/a= P1 + Ahpg/A= P1 + hpgNet pressure acting upwards = P2P2 = P1 + hpg or P2 - P1 = hpgTherefore, the pressure exrted by the liquid column on the bottom of the container is represented by hρg.please mark me brain mark list |
