The equipment has three water circuits with instruments, pipes and pipe fittings including a different valve on each circuit. The valves are downstream of each circuit to avoid upstream turbulence. The innermost of the three circuits has interchangeable sections that include the orifice, Venturi, Pitot, roughened pipe and the strainer. A mobile, space-saving vertical panel holds all the pipes and fittings for easy use. supplies the circuits with a controlled and measured flow of water. To measure pressure loss across each part, students use a piezometer set and differential pressure gauge (included). To adjust the datum water level in the tubes of the piezometer set, students connect a hand-pump (included) to the air valve above the tubes. To perform experiments students set the hydraulic bench to pump water through a circuit and measure pressure losses through the pipes and fittings. They also find the losses in a rapid enlargement and contraction. Several pipe sections are of different diameter to show how this affects pressure loss The Venturi meter and orifice plate instruments show students two common methods of measuring water flow. They also give applications of Bernoulli’s equation for incompressible fluid flow. Students use them to measure flow and compare the losses of each. The equipment also includes a Pitot-static tube. By traversing the Pitot across the pipe diameter, students can find the velocity profile and flow coefficients. They also find the relationship between the flow rate and pressure differential. An artificially roughened pipe allows students to study friction factor at different Reynolds numbers. They can compare results to those predicted by Nickuradse’s results and a Moody chart.
