Water falls down a vertical pipe by gravity alone. The flow between the vertical locations z1 and zz is fully developed, and velocity profiles at these twolocations are sketched in the figure. Suppose the vertical pipe is now horizontal instead. In order to achieve the same volume flow rate as that of thevertical pipe, we must supply a forced pressure gradient. Calculate and choose the correct equation for the required pressure drop between two axiallocations in the pipe that are the same distance apart as zz and z1.z = 72z = z1Multiple ChoiceP2 – PI = pg (z2 – z1) Multiple ChoiceP2 – P1 = pg (z2 – 21)P2 – P = pg (z2 + z1)P2 – P = pg ()P2 – P1 = pg (z2 × z1)
