Pick out the wrong statement pertaining to the turbine agitator.

Recommended peripheral speed for the turbine agitator is 200-250 metres/minute

Generally, the diameter of the agitator is kept between l/3rd to l/6th of the tank diameter while the blade length is l/4th of agitator diameter (with central disc, it is l/8th of the agitator diamete

Pitched blade turbine agitator gives only radial flow with complete absence of the axial flow

Turbine agitator should be located at a height not less than one agitator diameter length from the bottom. If the depth of liquid in the tank is more than twice the agitator diameter, two agitators sh
