a horizontal piece of pipeline carries a water in a streamline flow .at a point along the tube where cross sectional area is 1/100 sq.m, the water velocity is 2m/s and the pressure is 8000 pa. the pressure of water at another point where cross sectional area is 1/200sq.m
1dude , first find out whats the velocity of water flow at that 'another' point.
use : A1v1=A2v2 , where A represents area and v represents velocity.
now apply bernoulii's theorem. but mind it, h=constant.
so use : P + 1/2 ∂ v2 = constant ,where ∂ is standard density of water
now,see if u r not getting the answer.
11use Principal of Continuity,, after that Bernoulii's Theorem.
see if u r getting it ?
