The following particulars refers to a single row impulse turbine:

Mean diameter of blade ring = 2.5 m, speed= 3000 rpm, nozzle angle = 20ยบ, ratio of blade velocity to steam velocity = 0.4, blade friction factor = 0.8, blade angle t exit = 30 less than that at inlet, steam flow = 36,000 Kg/hr.

Draw a velocity diagram for moving blade and estimate

a) power developed

b) blade efficiency

c) steam consumption in Kg/KW.hr


Subject : Thermal and Fluid Power Engineering
