The accuracy of a fluid-flow measurement is directly relate to profit. Flow rate measurement devices require accurate pressure and temperature measurement in order to calculate the output of the instrument. Flow rate is express in Volume units (m³/s) and Mass units (kg/sec). The fluid can be corrosive, clean or dirty, single phase or multiple phase, laminar or turbulent. Hence, there are two types of devices, primary device (quantity meters) and secondary devices (rate meters). In this experiment, we will learn different types of flow meters devices to measure liquid (water) volume flow rate. The flow meters used on the apparatus are venturi meter, variable area meter and orifice plate. Base on table of data, please propose the design of experiments with the procedure. Their corresponding values for water flow rate are in the table below.

The accuracy of a fluid-flow measurement is directly relate to profit. Flow rate measurement
devices require accurate pressure and temperature measurement in order to calculate the
output of the instrument. Flow rate is express in Volume units (m/s) and Mass units (kg/sec).
The fluid can be corrosive, clean or dirty, single phase or multiple phase, laminar or turbulent.
Hence, there are two types of devices, primary device (quantity meters) and secondary
devices (rate meters). In this experiment, we will learn different types of flow meters devices
to measure liquid (water) volume flow rate. The flow meters used on the apparatus are venturi
meter, variable area meter and orifice plate. Base on table of data, please propose the design
of experiments with the procedure. Their corresponding values for water flow rate are in
the table below. By using that information, please indicate your answer for flowrate using
stopwatch and velocity at point 2 manometer (Venturi) (show the sample of calculation).
Area value is 1.77 x 10“ m².
