Lunchtime Mentoring: How a Drowned Orifice Works

We take mentoring very seriously here at T&H! During a lunch break, Senior Project Engineer James Hoyt, P.E. demonstrated to some of our junior engineers how a drowned orifice works as a connection between two adjacent tanks. The goal of the experiment was to prove that as long as the velocity through the connection remained low, the head loss through the connection would be low, and therefore the level in the first tank would not be significantly higher than the level in the second tank. This experiment was completed utilizing paper cups, straws, and chewing gum. We love to teach – and learn!
