A pipe is running full of water. At a point 'A' ; it tapers from $$200$$ $$cm2$$ cross $$-$$ sectional area to $$100$$ $$cm2$$ at other point 'B' . If the pressure difference between A and B is $$15$$ cm of water column; the rate of volume flow of water through the pipe is [$$g=10ms$$−$$2$$]

Question

A pipe is running full of water. At a point 'A'     ; it tapers from $$200$$ $$cm2$$     cross $$-$$ sectional area to $$100$$ $$cm2$$     at other point 'B'     . If the pressure difference between A     and B     is $$15$$ cm     of water column; the rate of volume flow of water through  the pipe is [$$g=10ms$$−$$2$$]

$$A1V1=A2V2$$       $$200V1=100V2$$⇒$$V2=2V1$$ $$p1$$−$$p2=$$ρ$$2(v22$$−$$v12)$$   $$15$$×$$10$$−$$2$$×$$103$$×$$10=10002(4v12$$−$$v12)1500=500$$×$$3v12$$            $$v1=1m/sRate$$ of flow $$=A1V1$$   $$=200$$×$$10$$−$$4$$×$$1=20$$×$$10$$−$$3m3/s$$   $$=20$$ $$lit/s$$

A pipe is running full of water. At a point $' A'$ ; it tapers from $200 c m^{2}$ cross - sectional area to $100 c m^{2}$ at other point $' B'$ . If the pressure difference between $A$ and $B$ is $15 c m$ of water column; the rate of volume flow of water through the pipe is $[g = 10 m s^{- 2}]$
