Flow Through An Orifice Manufacturer,Supplier and Exporter in India
Product Code : EL-FMP-11309
Quick Answer: The Flow Through An Orifice apparatus is a transparent cylindrical tank with a base mounting for different orifices, supplied with a sharp-edged orifice already fitted. It stands on the hydraulic bench and measures the decrease in flow, contraction of the stream and energy loss as water leaves the orifice.

Key Features
- Transparent cylindrical tank with a base mounting for different orifices
- Sharp-edged orifice supplied ready mounted
- Water enters from the hydraulic bench through an adjustable diffuser; an overflow pipe and the flow rate set the level
- Manometers measure the total head on the orifice and under the jet
- Traverse assembly places a Pitot tube anywhere in the jet
- Sharp blade measures the jet diameter for the contraction coefficient

About This Product
Students change the head on the orifice by adjusting the inflow, then measure the jet as it discharges into the hydraulic bench measuring tank. From these readings they work out the discharge, velocity and contraction coefficients for the orifice.
Frequently Asked Questions
How is the head on the orifice changed?
By adjusting the flow to the diffuser; the flow rate and an overflow pipe together set the water level in the tank.
How is the contraction coefficient found?
A sharp blade measures the jet diameter, which students use to find the contraction coefficient.
