Flow of steam through nozzles
WebA converging nozzle used in the stator of a high pressure steam turbine expands a steam mass flow rate of 1.0 kg/s. The nozzle inlet conditions of the steam are T = 500°C and P = 150 bar. The steam at the outlet of the nozzle is at a pressure of 100 bar. Note that for this expansion ratio the nozzle is not chocked. WebDec 26, 2024 · As states [1], the convergent nozzles with low roughness, practically have no friction pressure loss, and the flow of a liquid through them, is given by the equation …

WebA de Laval nozzle (or convergent-divergent nozzle, CD nozzle or con-di nozzle) is a tube which is pinched in the middle, making a carefully balanced, asymmetric hourglass shape. It is used to accelerate a … WebFlow through Steam Nozzles. 9/19/2024 4 Flow of Steam through Convergent-Divergent Nozzle 1. The steam enters the nozzle with a high pressure, but with a negligible velocity. 2. In the converging portion (i.e. from the inlet to the throat), there is a drop in the steam
Webleakage of steam through these is a direct loss of energy. Friction losses. Frictional resistance is offered during flow of steam through nozzles on moving and stationary blades. In most of the turbines the blade wheels rotate in a space full of steam. The viscous friction at the wheel surface causes admission losses as steam passes from nozzle ... WebQuestion: 4 Consider the reversible adiabatic flow of steam through a nozzle. Steam enters the nozzle at 1 Mpa and 300 °C with a velocity of 30 m/s. The pressure of the steam at the nozzle exit is 0.3 Mpa. Determine the exit velocity of the nozzle. 5 In problem #4, if the actual nozzle exit velocity is experimentally measured to be 500 m/s, determine: a) …
WebQuestion: Q6. Superheated Steam flows at steady state through a converging, insulated nozzle, 25 cm long and with an inlet diameter of 5 cm. At the nozzle entrance (state 1), the temperature and pressure are 240∘C and 350kPa and the velocity is 30 m⋅s−1. At the nozzle exit (state 2), the steam temperature and pressure are 325∘C and 700kPa.
WebMay 31, 2024 · A steam nozzle is a passage of varying cross-sections, which converts the heat energy of steam into kinetic energy. The main use of a steam nozzle is in a steam turbine, which produces a jet of steam with a high velocity. …. No heat is supplied or rejected by the steam during flow through a nozzle.
