8) The velocity of steam leaving the nozzle (V) is given by (where K = Nozzle coefficient or nozzle efficiency, and h_d = Enthalpy or heat drop during expansion of steam in a nozzle)

9) In a nozzle, whole frictional loss is assumed to occur between

10) The critical pressure ratio for initially wet steam is

11) The isentropic enthalpy drop in moving blade is two-third of the isentropic enthalpy drop in fixed blades of a turbine. The degree of reaction will be

12) The impulse reaction turbine has its driving force
