Steam issues from the nozzle of a single-impulse turbine at
800 m/sec on to blades moving at 300 m/sec. The blade tip angles
at inlet and outlet are 36º each. The steam is to enter the blades
without shock and the flow over the blades is frictionless.
(a) the angle at which the nozzles are inclined to the motion of the
(b) diagram efficiency.
following is the angle at which the nozzles are inclined to the motion of the
blades and diagram efficiency.
