WebEXPERIMENT 1: CALIBRATION OF 900 V-NOTCH. Aim: To find the coefficient of discharge (Cd) through a 900 triangular notch (V-notch) and. calibrate the notch. Theory: A notch may be defined as a sharp-edged obstruction over which flow of liquids occurs. The. sheet of water discharged by a notch is called Nappe or vein. Notches are used for. WebThe triangular notch has advantages over the rectangular notch since the shape of the nappe does not change with head so that the coefficient of discharge does not vary so much. A triangular notch can also accommodate a wide range of flow rates. ln (Q act.) = ln (C d. 8 15.tan(θ/2)."
