Issues Overcome. Each and every variety of turbine had its inherent difficulties to beovercome ahead of the specifications of commercial operationcould be met satisfactorily. In the reaction, or Parsons-sort,an critical supply of loss in efficiency is the steam leakingpast the ends of the blades without carrying out work. It is desir-capable, therefore, to lessen this loss to a minimum. The quan-tity of steam hence lost past a ring of blades depends uponthe peripheral length of the ring, the percentage that theclearance is of the length of the blades in the ring, and theclearance at the ends of the blades. Certainly, then, leak-age will be greatest more than the shortest blades. The impact ofspeed upon economy, here, is self-evident. Improve of speedand consequent lower In rotor- and cylinder-diameterB
