One end of a horizontal oil pipe is closed using valve and the reading of the barometer attached to the pipe is $$5$$×$$105pa$$ . When the valve in the pipe is opened the reading of the barometer falls to $$105pa$$ . The velocity of oil flowing through the pipe will be (density$$ of oil $$800$$ $$kg/m3$$ $$) in $$m/s$$

Question

One end of a horizontal oil pipe is closed using valve and the reading of the barometer attached to the pipe is $$5$$×$$105pa$$ . When the valve in the pipe is opened the reading of the barometer falls to $$105pa$$ . The velocity of oil flowing through the pipe will be (density$$ of oil $$800$$ $$kg/m3$$ $$) in $$m/s$$

Infinity Learn · Accepted Answer

$$P1$$−$$P2=12$$ρ$$v2$$⇒$$5$$×$$105$$−$$105=12$$×$$800v2$$⇒$$v2=4$$×$$105$$×$$2800$$                 $$v2=103$$⇒$$v=103$$⇒$$v=1010$$
