Suppose the tube in the previous problem is kept 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 = 10 m s-2.
Given, the length between the cross sections of A and B is 15/16 cm.
From the previous solution, velocity at A is
and velocity at B is
. These would remain the same as the same as changing the orientation doesn’t change the volume of water flowing from the tubes.
(c) From Bernoulli’s equation
![]()

Hence the pressure difference is
.
