About This Product
With water circulating in a closed loop between the tanks and the test section, the piezometer tubes show the pressure head at each tapping as the section converges and diverges. The flow rate comes from the measuring tank and stop watch, giving FLUID MECHANICS LAB students the data needed to check Bernoulli's theorem experimentally.
Frequently Asked Questions
Q1. How many piezometer tubes does it have? 9 P.U. piezometer tubes, connected through pressure tappings at different locations on the acrylic test section.
Q2. What power and water supply is needed? A 230 +/- 10 VAC, 50 Hz single phase supply with proper earthing (neutral to earth voltage less than 5 VAC) and a 5 A three pin socket with switch for the pump, plus a ½" BSP tap water connection. 60 litres of distilled water is optional.
