Orifice Mouthpiece Apparatus

An Orifice Mouthpiece Apparatus is also a device used for measuring the rate of flow of a fluid through a pipe. It also works on the same principle as that of venturi meter. It consists of a flat circular plate which has a circular sharp edged hole called orifice, which is concentric with the pipe. The orifice diameter is kept generally 0.5 times the diameter of the pipe, though it may vary from 0.3 to 0.8 times the pipe diameter

Scope Of Experimentations:

• Do not run the pump at low voltage i.e. less than 180 Volts
• Never fully close the Delivery line and By-Pass line Valves simultaneously
• Always keep apparatus free from dust
• To prevent clogging of moving parts. Run Pump at least once in a fortnight
• Frequently Grease/Oil the rotating parts, once in three months
• Always use clean water
• It apparatus will not in use for more than one month, drain the apparatus completely, and fill pump with cutting oil

Utilities Required:

• Water Supply
• Drain
• Electricity 0.5 kW, 220V AC, Single Phase
• Floor Area 1.5 x 0.75 m
