Answer:
a)True
Explanation:
While machining of ductile material and high feed and low cutting speed welding action take place between tool material and chip material this welding action is called built up edge. Built up edge action takes place due to high temperature.
To decrease the built up edge action
1. Increase the rake angle.
2. Increase the cutting speed
3. Decrease the feed rate
4. Use cutting fluid

Explanation:
The turbine is modelled after the First Law of Thermodynamics:
The rate of heat transfer between the turbine and its surroundings is:
The specific enthalpies at inlet and outlet are, respectively:
The required output is:
