lable heat drop (ti — U)n = number of stages.E = probable internal efficiency of each stage (about 60 to 70%). Example. Let it be required to lay out the blading for a Curtis type turbine having three pressurestages, each pressure stage to have two velocity stages. Initial pressure pi = 165 lb.… … EiFiclency 2384^29 Fig. 24. Velocity Diagram for Each Pressure Stage of a Curtis Type Turbinb. pressure Vi = 1 lb. Total heat drop i, - u = 326 B.t.u.
