Triangular and Rectangular Notch Tank Apparatus

Notches are openings cut in metallic plates are used for the purpose of measuring the discharge in stream. This apparatus is used to measure the coefficient of discharge of notches of various shape * V - Notch of angle 60o * Rectangular Notch of 100x150mm

 A Centrifugal pump of 25mm x 25mm with 1/2 HP Motor
 M.S. SUMP TANK 80 X 33 X 30cm to collect the water.
 M.S. MEASURING TANK 45 X 30 X 30cm fitted with piezometer tube to measure the discharge. Damper is used to collect the water in M. S. Measuring Tank for certain time.
 G.I. pipe of internal dia 25.4mm (1") and Gunmetal ISI mark Control Valve and regulating valves are used to circulate water.
 Bye-pass line is also used to regulate the discharge.

This apparatus consists of a rectangular tank of 80x40x20cm with rectangular opening at one end on which rectangular or V-Notch can be fitted with nuts. A pointer scale is used to measure the level of water in the tank.

The tanks are well epoxy painted inside to prevent rust hence increase the life of tank.

 Determination of coefficient of discharge of:
 90oC notch,
 Rectangular notch
 Trapezoidal
