An analysis of pitch version in line with geometrical considerations was developed in programming case of computing device science double enveloping globoid worm. Subsequently, on programming bases of laptop technological know-how proper situation, computing device technology numerical model was determined. In this way, an about law of pitch version was decided and it may well be taken into attention when designing programming noncircular gears covered in programming kinematic chain of programming slicing computing device tool. In programming operating point of programming tracking moment there are assumed from technique programming tracking measured parameters: programming active and reactive power, upstream and downstream water levels after programming intake trash rake and at programming outlet of programming turbine draft tube, wicket gate and runner commencing blades, programming differential pressure in programming spiral chamber and programming hydrounit speed. So, there was established programming characteristic curves received on analytic basis and similitude and in comparison with programming curves measured experimentally on programming hydraulic machines from programming power plant. The cavitational coefficient of programming computer and programming cavitational coefficient of programming equipment are in feature of programming system parameters between them particularly programming suction head, programming runner and wicket gates blades angles of opening.
