I have watched a video of engine balancing in which the Technician told that the in engine balancing they make the counter weight= Rotary mass+Half of reciprocatory mass..Why full reciprocatory mass is not taken..and what are the impacts of taking full reciprocatory mass.
I have heard mechanics saying that in engine balancing ,Engine builders could under balance an engine or over balance an engine to in specific limits .and under balancing increases the acceleration while in over balancing the engine works best at higher rpm is it true that engine is under...
I have read that the throttle valve(Governor valve) in the Rankine cycle is used to reduce the pressure but keeps the enthalpy equal for the inlet and outlet.
H=U+Pv
pressure is decreased so I get it ,It would increase the kinetic energy but what about the Potential energy would it also be...
Why turbine is unable to work in a mixed vapor region. I have heard maintenance cost increases but what happens inside it that it could operate in a superheated region but not in mixed vapor region
Does the blades of the turbine increase entropy of steam passing through it .then why are the turbines 70-90 on isentropic efficiency .There is a volume change taking place as well as pressure change. How is turbine so isentropic efficient??
