A venturi meter is a device that is used for measuring the flow rate of a fluid within
a pipe. Gas is flowing at speed v2 through a horizontal section of pipe, as shown in the
figure below, whose cross-sectional area is A2 = 0.0700 m2. The gas has a density of p =
1.30 kg/m. The venturi meter has a cross-sectional area of A1 = 0.0500 m2 and has been
substituted for a section of the larger pipe. The pressure difference between the two sections
is p2- P1 = 120 Pa. Find: (a) Find the speed vy of the gas in the larger, original pipe. (b)
Find the speed vị in the venturi. (c) Find the volume flow rate O of the gas.

Problem-4: An inverted hollow container with a uniform cross section area, A and height, H is
slowly pushed into water as shown. The water rises into the container by a distance l (and
compresses the air inside isothermally) as the cylinder is submerged into water by distance, d as
shown in the schematic.

and H).
