Question Bank 1) Find out the diagram efficiency of an impulse turbine supplied with steam at the rate of 30 kg/min through nozzles. Steam entering the nozzle inlet is at 5 bar and 2000C while the condenser pressure is 0.2 bar. Nozzles are inclined at 250 to direction of motion of the blades which are ?Turbomachines involve a collection of blades, buckets, flow channels, or passages arranged around an axis of rotation to form a rotor. ?Turbomachines are mechanical devices that either extract energy from a fluid (turbine) or add energy to a fluid. (pump) as a result of dynamic interactions between the device and the fluid 15 Apr 2013 existing impulse turbine, a one-stage turbine set in an organic Rankine cycle with the working fluid being. R245fa. Various Leaving the isentropic calculations, the work by Tournier, “Axial flow, multi-stage turbine and compressor models" [18] In order to remedy this problem, the results were compared to results obtained Turbine blades, and hence turbines having these types of blades, are classified as impulse or reaction. When moving blades are driven entirely by the impact of an external jet impinging upon them, they are known as impulse blades. When the fluid in the moving blades accelerates and leaves the blades at a higher velocity Make an observation that out of the 10 solved examples and the 8 exercise problems of this chapter, only 4 problems required the reference to the Mollier Diagram (enthalpy–entropy chart for steam). Locate these four problems. Then, take a Mollier diagram and mark all the four isentropic expansion processes (not actual The degree of reaction of a turbine stage (stator nozzles plus rotor blades) is the fraction of the fluid static enthalpy drop which occurs in the rotor (see section 2. of this Lecture). In an impulse turbine, the degree of reaction is zero, meaning that the gas expands and accelerates as it turns in the stator passages, and then is The motive power in a steam turbine is obtained by the rate of change in momentum of a high velocity jet of steam impinging on a curved blade which is free to rotate is free to rotate. ? The conversion of energy in the blades takes place by impulse, reaction or impulse reaction principle. ? Steam turbines are available in a In short, in purely impulse turbines the rotary motion of the shaft is obtained by having high velocity jets of steam directed against . For convenience in solving problems on turbine blades, it is usual to . Problem-1 : Steam issues from the nozzle of a simple impulse turbine with a velocity of 900 m/sec. The nozzle angle is The external diameter of an inward flow reaction turbine is 0.5 m. discharge through turbine and the width of wheel at outlet. find ($
