|Velocity ratio for impulse turbine = 0.5 cosθ.
Velocity ratio for reaction turbine = cosθ.
|Yashfa said: (Jul 23, 2016)|
|How is this possible?|
|Pal said: (Aug 19, 2016)|
|The answer should be the option (a).|
|N Suresh said: (Dec 6, 2016)|
|When the efficiency of reaction turbine is maximum where blade velocity should be half. So that Vb = 0.5 V cos a.|
|Vijay said: (Dec 22, 2016)|
|Maximum efficiency is option B because (Vb/v)= cos.|
|Biplab said: (Dec 31, 2016)|
|For reaction turbine, max efficiency condition is cos alpha and in case of impulse turbine (cos alpha)/2.|
|K910 said: (Feb 7, 2020)|
|The answer is correct for rxn it is U/V=cos alpha for impulse it is cos(alpa)/2.|
