Top 12 Turbines Exceptional Viva Question with Answers 2018
This video section contains turbines exceptional top 12 questions which are very important for fresher mechanical / experience engineer persons for taking job preparation.
Here we discuss top 12 turbine exceptional question with answer. These exceptional questions are very important for power plant viva, diploma interview, B.Sc engineering viva, sessional viva etc.
#turbine, #reactionturbine, #steamturbine,
Here list up some important questions with answer:
Question Number 1: What is turbine heat rate?
Answer: It the ratio of heat input to MW generated in kcal/kWh.
= steam flow (enthalpy of steam-enthalpy of feed water) / MW.
Question Number 2: What are the turbine losses?
Answer: The turbine losses are mention here as,
a)Tip Leakage loss- This loss is happen due to the clearance in between the fixed and moving blades.
b) Friction loss- This loss is due to the fluid friction in nozzle and rotor blades.
c) Leaving loss- This loss is considered due to the leaving of steam in last stage of blade without doing further useful work.
Question Number 3: why maximum steam turbine double shell casing is provided?
Answer. The double shell is preferred because,
a) for quick start up of turbine.
b) Less stress developed in the casing due to double casing.
Question Number 4: What are the types of condenser used in steam turbine?
Answer. There are two type of condenser is general used in steam turbine as,
a) Jet condenser: - In this type of condenser exhaust steam and cooling water is directly mixing together. Here very high quality of cooling water is needed. The quantity of cooling water required is very less as compared to surface condenser.
b) Surface condenser:- Here the cooling water is flowing through tube shells and the exhaust steam is cooled through the contact of cooling water tubes
Question Number 5: What is vacuum?
Answer. The vacuum can be defined as a state of very low pressure or we can say that a space of no matter. It is below the atmospheric pressure and measured in (mmHg).
