If nozzle angle is 30°, the De Laval turbine will have a maximum efficiency of
Steam enters a De LavaI steam turbine with an outlet velocity of 25 m/s and leaves with an outlet velocity of 5 m/s. The work done by 1 kg of steam is
A single stage impulse turbine with a diameter of 100 cm runs at 3000 rpm. if the blade speed ratio is 0.45, the inlet velocity will be
For a single stage impulse turbine with nozzle angle 15°, rotor diameter 2 m and speed 3000 rpm, the optimum velocity of steam in m/s is:
[Take cos15° = 0.966, sin15° = 0.258]
For an impulse turbine, the nozzle efficiency is 90%, the blade velocity ratio is 0.5 and the mean blade velocity is 150 m/s. This corresponds to heat drop in the nozzle equal to
