Analysis of the Chain Turbine by (Nguyen Minh Duy)

With flow rate is 1m3/s, and the head is 20m.
Assume H1=19m, H2=1m, the diameter of the sprocket is 1m.

The gross power output:

Apply the principle of work and energy with the bucket of chain turbine:

The maximum speed of bucket

The angular velocity the sprocket would be

The rotational speed of the sprocket would be

Number of buckets in chain turbine

The power output is

The power out of the turbine shaft

The efficiency of the chain turbine is given by
