About This Product
The three hydraulic coefficients describe how real flow through a small opening differs from the ideal case. Students set a head with the overflow pipe, adjust the discharge and take X and Y readings with the sliding pointer, then repeat the run for each orifice and mouthpiece. Comparing the results shows how the coefficients vary under different operating conditions, and that is the aim of the experiment. The Orifice And Mouthpiece Apparatus can be packed for export to Cameroon, Palestine, Samoa, the Central African Republic, Vanuatu and New Zealand.
Frequently Asked Questions
Which hydraulic coefficients can be found?
The coefficient of discharge, the coefficient of contraction and the coefficient of velocity, studied at variable heads for each of the given orifices and mouthpieces.
How is the head changed?
A chrome-plated overflow pipe changes the head, and the flow control valve changes the discharge. Head is read on transparent piezometer tubes with scale.
