Parshall Flume Apparatus

The Parshall Flume Apparatus is an educational hydraulic laboratory accessory developed for practical investigation of open-channel flow and discharge measurement using a specially shaped channel.

A Parshall flume is a fixed hydraulic structure consisting primarily of a converging section, throat section, and diverging section. The changing channel geometry creates predictable variations in water depth and velocity that can be used to study and determine open-channel discharge.

The apparatus is designed for installation in a compatible experimental flume or open-channel laboratory system.

As water enters the converging section, the available flow area changes and the water accelerates toward the throat. The flow then passes through the restricted throat section before entering the diverging downstream portion.

This configuration allows students to clearly observe changes in flow depth, velocity, and water-surface profile throughout the apparatus.

One of the primary applications of the Parshall Flume Apparatus is the measurement and study of open-channel discharge. Water-depth readings can be taken at suitable measuring locations and related to the corresponding flow rate.

Experiments can be conducted at different flow conditions to investigate the relationship between upstream water depth and discharge.

The apparatus also provides practical understanding of how channel contraction affects flow velocity. Students can observe acceleration through the converging section and changes in flow behaviour through the throat and downstream section.

Water-surface profiles can be observed throughout the experimental region, making the apparatus useful for understanding hydraulic transitions in varying channel geometries.

The system can also be used to compare experimentally observed discharge with theoretically determined or calibrated values where suitable measurement arrangements are available.

The Parshall Flume Apparatus provides practical understanding of open-channel flow measurement, discharge, channel contraction, flow acceleration, water-depth variation, throat flow, and hydraulic control structures.

Micro Technologies supplies Parshall Flume Apparatus and compatible experimental flume accessories for engineering colleges, universities, polytechnic institutes, technical training centres, and hydraulic engineering laboratories.

FAQs

What is the Parshall Flume Apparatus used for?

The apparatus is used for practical study of open-channel flow and discharge measurement while investigating changes in water depth and velocity through a Parshall flume.

What is a Parshall flume?

A Parshall flume is a specially shaped open-channel flow-measuring structure consisting of converging, throat, and diverging sections.

Can discharge be measured using the apparatus?

Yes. Water-depth measurements at specified locations can be related to flow rate for determining or studying open-channel discharge.

What are the main sections of a Parshall flume?

The principal sections are the converging section, throat section, and diverging section.

Can water-depth changes be studied?

Yes. Students can observe and measure variations in water depth as the flow passes through the different sections of the flume.

Can flow velocity be studied?

Yes. The changing channel geometry produces changes in velocity, allowing students to investigate flow acceleration and related hydraulic behaviour.

Can the water-surface profile be observed?

Yes. When installed in a suitable laboratory channel, changes in the water-surface profile can be observed throughout the Parshall flume.
