Numerically controlled machine tools are better suited for .................. (batch/mass) production, because their setup time is ......... (larger / smaller) in comparison to special purpose machine tools.

In a Rankine cycle heat is added

Velocity compounded steam turbine known as ___________ (Curtis / Rateau ) turbine uses the principle of converting entire __________ (pressure / velocity) energy before entering the first stage runner itself.

In a single heater regenerative cycle, steam enters the turbine at $$30$$ bar, $${300^0}C$$ and condenser pressure is $$0.096$$ bar. The feed water heater is a direct contact type which operates at $$5$$ bar. Draw flow and $$h$$-$$s$$ diagrams considering the condition of steam at entry to the heater in mixture region. Calculate steam extracted from heater to turbine in $$kg$$ per $$kg$$ of steam flow the cycle and cycle efficiency. The enthalpies of steam at different locations of the cycle are given in a table below. Pump work may neglected.
