Coriollis Component Of Acceleration
Product Code : EL-TOML-11027
Quick answer: The Coriolis component of acceleration apparatus determines the Coriolis component at different speeds using a hydraulic analogy of a slider moving along a rotating link. Water flows out through two opposite rotating arms driven by a 0.5 HP swinging field DC motor, which also measures the torque. A rotameter gives the flow. Lab Exports manufactures it in Delhi for engineering colleges, polytechnics and TVET institutes.

How the Coriolis component experiment is done
When a slider moves outward along a link that is itself rotating, the slider has an extra acceleration at right angles to the link, the Coriolis component, equal to 2 x omega x v, where omega is the angular speed of the link and v the sliding velocity. It appears in quick-return mechanisms, slider crank analysis and any rotating arm with radial motion.
On this apparatus, water leaving through the rotating arms plays the part of the slider. The rotameter flow and the bore of the arms give the water velocity v, and the speed indicator gives omega. The Coriolis force on the water resists rotation, so the swinging field motor shows an extra torque when water flows. Comparing it with the theoretical value, rho x Q x omega x L^2 for a total flow Q leaving arms of length L, verifies the 2 x omega x v relation.
- Start the monoblock pump and set the water flow on the rotameter.
- Run the arms at a set speed with the speed control unit and read the speed indicator.
- Note the torque on the swinging field motor with and without water flow.
- Repeat at other speeds and flow rates.
- Compare the measured torque with the calculated Coriolis torque.

Frequently asked questions
How does the apparatus represent the sliding block?
Water flowing outward through the rotating arms acts as the slider, so the Coriolis effect shows up as an extra torque on the drive.
How is the torque measured?
The swinging field DC motor works as a dynamometer: the reaction on its casing gives the torque needed to turn the arms.
