Mechanical Engineering :: Steam Nozzles and Turbines
- In an experiment to determine dryness fraction of steam, the mass of water separated was 1.2 kg in 15 mts. and the mass of steam passed out in same time was 4.8 kg. Dryness fraction is
- One kg of steam sample contains 0.8 kg dry steam? Its dryness fraction is
- Hard coke is produced by carburization of coal at
- When the back pressure of a nozzle is below the designed value of pressure at exit of nozzle, the nozzle is said to be
- When the nozzle operates with the maximum mass flow, the nozzle is said to be
- The maximum discharge of steam through a convergent-divergent nozzle depends upon
- The variation of steam pressure in the nozzle depends upon
- The efficiency of an impulse turbine is maximum when (where Vb = Blade speed, V = Absolute velocity of steam entering the blade, and α = Nozzle angle)
- The maximum efficiency of a De-Laval turbine is (where α = Nozzle angle)
