The annular venturi meter is useful for metering flows in pipe systems for which upstream calming distances are limited. The annular venturi meter consists of a cylindrical section mounted inside a pipe as shown in the figure. The pressure difference is measured between the upstream pipe and at the region adjacent to the cylindrical section. Air at standard conditions flows in the system. The pipe diameter is 10 cm. The ratio of the cylindrical section diameter to the inside pipe diameter is 0.8. A pressure difference of 5 cm of water is measured. Find the volume flow rate in the system. Assume the flow is incompressible, inviscid, and steady and that the velocity is uniformly distributed across the pipe sections. Use standard condition for air at 25oC and 101 kPa

Question

The annular venturi meter is useful for metering flows in pipe systems for which upstream calming
distances are limited. The annular venturi meter consists of a cylindrical section mounted inside a pipe
as shown in the figure. The pressure difference is measured between the upstream pipe and at the
region adjacent to the cylindrical section. Air at standard conditions flows in the system. The pipe
diameter is 10 cm. The ratio of the cylindrical section diameter to the inside pipe diameter is 0.8. A
pressure difference of 5 cm of water is measured. Find the volume flow rate in the system. Assume the
flow is incompressible, inviscid, and steady and that the velocity is uniformly distributed across the pipe
sections. Use standard condition for air at 25oC and 101 kPa
