Suppose the tube in the previous problem is kep vertical with A upward but the other conditions remain the same. The separation between the cross sections at A and B is 15/16 cm. Repeat parts a., b, and c of the previous problem. `take g=10ms^-2`.

Answer» Correct Answer - A::B::C::D
a. `v_A =25cm/sec`
`b. v_B=50cm/sec`
c. From Bernoullis equation
`1/2pv_A^2+rhogh_A+pA=1/2pv_B^2=rhogh_B+pB`
`rarr P_A-P_B=(1/2)p(v_B^2-v_A^2)+rhog(h_B-h_A)`
`[Given h_A-h_B=(15/16)cm]`
`rarr P_A-P_B=1/2(2500-625)-1000x15/16`
