Medium head. 60-300m - Francis turbine.

High head >300m - Pelton turbine.

The ascending order is the turbine used according to head is Pelton wheel tb, Francis tb, Proppler tb. Kaplan turbine is a kind of reaction turbine as francis turbine. So the answer is pelton wheel turbine.

Francis is low head (10-60m) Kaplan medium head (60-300m) &Pelton is the high head (300-2000m).
