The steam bench incorporates four similar mild steel tubes, each connected to a common steam supply via an inlet regulating valve and a common blowdown line via an outlet valve. Two of the tubes are unlagged but have differing finishes, namely a painted finish and a chromium plated finish respectively. Lagging Efficiency Steam Bench consists of a sturdy framework and panels of all steel construction, fitted with a student work surface, interconnecting back panel and adjustable feet. The measured temperatures are displayed on an analogue temperature meter via a selection switch. From measurements of temperature and condensate levels over a period of time, students are able to calculate the lagging efficiency and the coefficient of thermal conductivity of the lagging. The remaining two tubes are lagged, one with glass fibre webbing tape and the other with a pre-formed fibre glass insulation jacket. Each tube is fitted with a sight glass and scale to enable condensate to be measured.

The impulse swirl meter uses a swinging honeycomb type matrix which is restrained from rotation by a strain-gauged load cell to totally arrest the angular swirl component thereby measuring the resultant angular impulse as a torque. Earlier methods of measuring swirl such as swirl vane meters, were dependent on the velocity profile of the air stream, whereas the impulse type of meter overcomes this limitation by responding to the total angular momentum flux in the swirling air flow.
