water flow alonga horizontal pipe of variable cross section. At a point where the velocity of flow is 0.3 m/s , the pressure is 1400N/m^2 . What is the pressure at the point where the velocity of flow is 0.6 m/s ? |

Answer» Solution :A =` 0.01m^2 x = 0.2cm = 0.002 m v = 0.03 ms^-1`Horizontal force to move the plate `F = (etaAv)/(x) = (1.55 XX .01 xx 0.03)/(.002)` = 0.2325 N. |
