Five types of devices are studied in this experiment. Orifice plate, with central hole in a blind flange; Nozzle, like orifice plate but the hole extended by a short pipe segment; Venturi tube, with converging and diverging bells; Pitot tube, involving adjustable radial position thin L-shaped tube and Iris valve, like adjustable diameter orifice plate, are studied using controlled delivery air blower. The air flow creates a pressure drop across the device. The flow rate and corresponding pressure dropare measured and plotted for the various devices.Aim: To study pressure drop characteristics of various air flow measuring and controlling devices and verify theoretical equations.Experimental Procedure: 1)The given device is bolted by flanges between two PVC pipe sections of 84.6mm NB.2)The necessary pressure tapping points are connected to manometer(s) by rubber tubes.3)The air blower is started and controlled at potentiometer settings of 2 to 8.4)The air velocity is measured with anemometer.5)The resulting pressure drop is measured as difference in water columns of manometer.6)The water column pressure drop is converted to Pascal units and various plots are made.Results:A)Nozzle CharacteristicsPotentiometerh (mm)p (N/m2)sqrt(p) (N0.5/m)Velocity (m/s)2439.26.31.43878.58.92.1415147.212.12.8523225.615.03.5633323.718.04.2746451.321.25.0863618.024.96.0
