INTRODUCTION: In many industries, the measurement of the flow rates in pipes or channels is important for many applications. For this purpose, there are many devices used to measure the flow rate. For example: a Pitot tube, a Venturi, and an Orifice. For measuring “point” velocity, the Pitot tube usually used for this purpose.

Then, the manometer was connected to the desired flow meter. Then, the pump was started against the discharge valve. The flow rate was measured by timing the level rise in the calibration tank and five measurements were taken for each flow meter. This procedure was repeated for the other two devices....
