5- Steam at an absolute velocity of 750 m/s is directed on blades of an impulse turbine at an angle of 22° to their motion. The blades speed is 225 m/s, exit angle of the blade is 31° and the friction between the steam and blade surface reduces the relative velocity of the steam by 15% if the steam flow rate is 3.72 T/hr, Calculate: i. The Stage power and efficiency. ii. The inlet angle of the balding. iii. The magnitude and direction of the absolute velocity of the steam at exit from the blades. 5- Steam at an absolute velocity of 750 m/s is directed on blades of an impulse turbine at an angle of 22° to their motion.
