- Q2. Why Turbine,s efficiency is less & so derive the efficiency equation
- Ans.
The efficiency of a turbine is less due to various factors such as friction, heat losses, and mechanical losses.
Friction between the moving parts of the turbine reduces its efficiency.
Heat losses occur due to the conversion of thermal energy into mechanical energy.
Mechanical losses include losses in bearings, seals, and other components.
Efficiency equation: Efficiency = (Useful output energy / Input energy) * 100%
