a high velocity jet. This jet of steam impinges on the moving vanes or blades, mounted on a shaft. Here it undergoes a change of direction of motion which .. PEMP. RMD 2501. Work Done – Impulse Steam Turbine. Differentiating equation (12) and equating it to zero provides the maximum diagram efficiency;. 0. 8 cos4. )( =.
Design Of steam turbine. Velocity Diagram. In impulse turbine all calculations are made by velocity diagram.first we will consider inlet velocity diagram and another outlet velocity Diagram. Nozzle through which the steam is flowing and when the steam flows through this nozzle, there will be a drop in the pressure and there
Velocity diagram of an impulse turbine: In an Impulse turbine, the jet of steam leaving the nozzle enters into the turbine blade and then glides over the inner surface of the turbine blade and finally leaves from the outer edge of the blade. Consider the steam jet entering the turbine blade at the top and leaves the blade at the
Check, whether the exit velocity, together with generated velocity, gives rise to the entry velocity; and if not, by how much it differs. Complete your project by calculating the efficiencies and the reheat factor. Solution: The problems, involving the use of Mollier diagram (enthalpy–entropy chart for steam) are: Solved Examples
Steam Turbines. 6.1 INTRODUCTION. In a steam turbine, high-pressure steam from the boiler expands in a set of stationary blades or vanes (or nozzles). .. Thus, when a2 ? a1, the reaction is unity (also C1 ? C2). The velocity diagram for L ? 1 is shown in Fig. 6.20 with the same value of Ca, U, and W used for. L ? 0 and
Velocity diagram for moving blades : Fig. 9-3(a) shows the nozzle and blades either of single-stage impulse turbine or of one stage of a multi-stage turbine. Steam enters the nozzle at pressure p0 and issues from nozzle at pressure pi. The velocity of the steam at the nozzle exit is Vi and it is at an angle ai to the tangent of the
