Document Summary
Solution to part (a): we use the equation of continuity in the form: in which the index con refers to the constricted section of the pipe. The second equation we use is bernoulli"s equation in the form: (1) We combine both equations by separating the speed of the fluid in the constriction, vcon, in eq. Then we solve for the speed v. we begin by abbreviating the pressure difference as p = p pcon and by combining the terms which contain v on the right hand side: (3) (2) [5], in turn, is related to the height difference of the liquid in the centre and left glass tubes by pascal"s law, p = liquid a g a h. Replacing p, we get the equation given in the problem text. Confirm also that the brackets as set in eq. [5] are consistent with those in the problem text equation.
