The steam from the nozzles of a single wheel impulse turbine discharges with a velocity of 600 m/s at an angle of 20 degrees. The blade wheel rotates at 3000 rev/min and the mean blade radius is 590 mm. The axial velocity of the stream at the exit from the blades is 164 m/s and the blades are symmetrical.
Sketch the annotated velocity triangles and calculate:a) the blade inlet angleb) the diagram specific workc) the diagram efficiencyd) the blade velocity coefficiente) Show that for symmetrical blading and no friction n_rot = 4(U/V_1)(cos(alpha_1) - (U/V_1)) and determine the optimum blade speed ratio and efficiency. Make a sketch of your results.
Calculation of percentage heat reduction, Water at 90 C flows through a 50mm bore steel pipe of wall thickness 8 mm. Ambient temperature is 18 C. Calculate the heat loss per metre length of pipe
Water is the working fluid in an ideal Rankine cycle. Saturated vapor enters the turbine at 18 MPa. The condenser pressure is 6 kPa. How do I determine the quality of the fluid at the turbine exit
Evaluate the effect of the water spray on efficiency (net work out divided by heat input) and net power out per kg/s of dry air coming into the turbine.
