![11. A turbine of 9000 B.H.P. is working under a head of 25 m
and runs at 100 R.P.M. What will be the type of turbine ? What
should be its speed and power, when it is working under a head of
[Ans. Francis, 80 and 4610 H.P.J
16 m ?
12. A Kaplan turbine of 100 B.H.P. is working under a head
of 5 m and running at 210 R.P.M. The discharge through the tur-
bine is 1'80 m³/sec.
If now the turbine is allowed to work under a head of 15 m,
what would be its new speed, discharge and power ?
[Ans. 364 R.P.M., 3.12 m³/sec and 519 B.H.P.]
13. A scale model of 1 is used to determine the design of a
turbine to develop 10,000 B.H P. under a head of 9 m of water run-
ning at a speed of 100 R.P.M. The head available in the laboratory
is of 6 m and overall efficiency is 88%.
Calculate:
(i) Speed, (ii) Discharge, (ii) Power required by model.
[Ans. 816 R.P.M., 770 litre/sec and 54'5 B.H.P.]](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0728d9f6-697f-4155-b3af-07d624a7dbc2%2F33ea80d9-a6e5-4010-b97e-68f6ec0eb336%2Fhzciwdj_processed.jpeg&w=3840&q=75)
