solve 2 questions.

b) A Pelto. whicel iunning at 260 s.p.m. and opcrating under an available head of 250m is required oo deveiop 2.5M. . . There is only one jet with nozzle diamcter 15cm and the bucket deflection angle is 165. The co-efficicnt of velocity of nozzle =0.98 and blade specd ratio =0.46. Deiermine the following: i) The Turbine Efficiency ii) Bucket pitch circie diameter iii) Hydraulic efficiency of the turbine. (10) b) The following data are given for a centrifugal pump: Outcr diameter 2 Internal diameter Speed =3000 r. p. m. Internal Diameter =100mm. Width of Impeller at outct =20mm. Blade angle at outlet =30 Flow velocity at inlet = Fow velocity at outlet =3m/s Manometric Efficlency =80% Overall Efficiency =70% i) inlet vane angle ii) The rate of discharge iii) The magtratric ifiviens. iv) The shaft power
