Abstract
GAS FLOW IN AN OBLIQUE TIP OF SINGLE NOZZLES AND TURBINE NOZZLES: Formulas are derived for determining the deflection of a stream in an oblique tip of an unprofiled diverging nozzle and for nozzle blading with an edge of finite thickness. The critical pressure ratio in nozzle blading with an edge of finite thickness is greater than in single nozzles and can be taken into account when calculating the characteristics of motors, including turbine machines. SIMULATING THE OPERATION OF A CENTRIFUGAL PUMP USING AIR: The performance of a liquid pump can be plotted with an accuracy by simulating the operation of the pump by using air. The drive power of the test pump operating on air was by a factor of about 85 less than the power required by the same pump operating on water. The results can be used in the experimental treatment of new centrifugal pumps of high efficiency whose flow sections have a complex form.
