A pair of vertical, open-ended glass tubes inserted into a
horizontal pipe are often used together to measure flow
velocity in the pipe, a configuration called a Venturi meter.
Consider such an arrangement with a horizontal pipe
carrying fluid of density p. The fluid rises to heights h₁ and
h₂ in the two open-ended tubes (see figure). The cross-
sectional area of the pipe is A₁ at the position of tube 1,
and A2 at the position of tube 2.

A hydraulic piston has two surfaces which can move when a force is applied to them. On the left side, the piston surface is circular with a cross-sectional radius of 10 cm and on the right side it is square with a side of length 30 cm. A. If I push on the left side with 100 N of force, what total force will be exerted by the fluid in the piston on the right side? B. If I displace the piston on the left side by 18 cm, how far will the right surface move?

The water level on the side of the manometer which is open to the air is 12.2 cm higher than on the side connected to the balloon. a. Find the gauge pressure in the balloon, in units of Pa.
