Flow Through Orifice and Mouthpiece Apparatus
Model Number: MTFM-102
The Flow Through Orifice and Mouthpiece Apparatus is an educational fluid mechanics laboratory system designed to determine the coefficient of discharge of different orifices and mouthpieces and the coefficient of velocity of a water jet. The apparatus enables students to study flow through small openings, jet behaviour, theoretical and actual discharge, and fundamental hydraulic coefficients through practical experimentation.
Product Specification
The Flow Through Orifice and Mouthpiece Apparatus is a laboratory teaching system developed for the experimental investigation of water discharge through different types of orifices and mouthpieces.
Manufactured by Micro Technologies, the apparatus provides a practical method for studying the relationship between pressure head, theoretical velocity, actual jet velocity, theoretical discharge, and actual discharge.
An orifice is an opening generally provided in the side or bottom of a vessel through which liquid is discharged. A mouthpiece is a short tube attached to an opening and can influence the contraction, velocity, and discharge characteristics of the emerging liquid.
The apparatus incorporates a constant or variable head water tank with provision for mounting interchangeable orifices and mouthpieces. Water discharged from the selected opening forms a free jet that can be observed and measured.
Different test pieces can be installed to compare their flow characteristics under controlled operating conditions.
The coefficient of discharge (Cd) can be determined by comparing the experimentally measured actual discharge with the theoretical discharge calculated from the available water head.
The apparatus can also be used to determine the coefficient of velocity (Cv). The trajectory of the water jet emerging from the opening can be measured at suitable horizontal and vertical coordinates, allowing actual jet velocity to be evaluated.
These experiments help students understand why actual fluid-flow behaviour differs from ideal theoretical predictions due to effects such as contraction, viscosity, friction, and other hydraulic losses.
The apparatus provides an effective practical demonstration of fundamental fluid mechanics principles and is suitable for routine student experiments, engineering demonstrations, and laboratory examinations.

FAQs
What is a Flow Through Orifice and Mouthpiece Apparatus?
It is an educational fluid mechanics apparatus used to study water discharge through different orifices and mouthpieces and determine important flow coefficients experimentally.
What are the main experiments performed?
The primary experiments are the determination of coefficient of discharge for different orifices and mouthpieces and the determination of coefficient of velocity.
What is an orifice?
An orifice is an opening through which a fluid discharges from a tank, vessel, or pipeline under an available pressure or hydraulic head.
What is a mouthpiece?
A mouthpiece is a short tube or passage attached to an opening and used to study how outlet geometry affects flow and discharge characteristics.
What is coefficient of discharge?
Coefficient of discharge is the ratio of actual fluid discharge to the corresponding theoretical discharge.
What is coefficient of velocity?
Coefficient of velocity is the ratio of the actual velocity of the emerging jet to its theoretical velocity.
Can different orifices and mouthpieces be tested?
Yes. The experimental arrangement can accommodate suitable interchangeable test pieces for comparative studies.
Can the water jet trajectory be studied?
Yes. The emerging jet can be observed and measured to investigate its trajectory and determine actual jet velocity.
Why is actual discharge different from theoretical discharge?
Real flow is affected by viscosity, contraction, friction, flow separation, and other losses, causing actual discharge to differ from ideal theoretical values.
Is this apparatus suitable for engineering colleges?
Yes. It is suitable for civil, mechanical, hydraulic, water resources, chemical, process, and fluid mechanics engineering laboratories.
