In a reaction stage of a steam turbine the nozzle angle is 20° and the absolute velocity of the steam at inlet to the moving blades is 240 m/s. The blade velocity is 210 m/s. If the blading is designed for 50% reaction, determine: (i) the blade angle at inlet and exit; Gl the cothalpy drop per unit mass of steam in the moving blades and in the complete 1.7 stage; (iii) the diagram power for a steam flow of 1 kg/s: (iv) the diagram efficiency.

At a particular stage of a reaction turbine the mean blade speed is 140 m/sec and the steam is at a pressure of 20 bar with temperature of 250° C.

In a trial run, the De Laval steam turbine at Oman Power Plant rotates at 3000 rpm. The steam is issued from the nozzle at 400 m/s and the nozzle angle is 20o. The blade speed ratio is 0.41and the friction loss in the blade channel is 15%of the kinetic energy corresponding to the relative velocity at the inlet to the blades. As a turbine engineer at that station, how do you determine the (i) power developed by the turbine for a flow rate of 10 kg/s and (ii) suitable inlet and outlet angles for the blades when axial thrust is zero. Also, how would you determine the size of the turbine wheel required? Draw a suitable velocity diagram.
