With regard to radial gas turbine efficiency, which of the following statements are correct?


1-Rotor loss coefficients usually lie in the range from 0.063 to 0.235


2-The conventional way to determine total-to-total efficiency is to first find total-to-static efficiency and then use that value in calculating total-to-total efficiency.


3-Total-to-static efficiency is relevant when use will be made of the kinetic energy of the exhaust gasses.


4-The stagnation enthalpy is reduced across the diffuser because of the gain in entropy.


5-The trigonometry term cosec x is the same as 1/cos x .
