ME8792 PPE POWER PLANT ENGINEERING
1.State thermodynamic law:
1. Zeroth law refers to thermodynamic equilbrium and temperature
2. First law refers to heat, work and energy
3. Second law refers to entropy
2.State zeroth law of thermodynamics:
“Two systems in thermal equilbrium with a third system are in thermal equilbrium with each other”
3.State Fitst law of thermodynamics and energy conversion.
The first law of thermodynamics is often called as Law of conversion of energy. This law suggests that energy can be transferred from one system to another in many forms. Also, it cannot be destroyed or created.
4.State second and third law of thermodynamics:
The second law of thermodynamics another state variable called entropy. In any closed system, the entropy of the system will either a thermodynamic process, the system can never completely return precisely the same state it was in before. The third law of thermodynamics states that if all the thermal motion of molecules(kinetic energy) could be removed, a state called absolute zero will occur. Absolute zero results in a temperature of 0 kelvin or -273.15 cellcius.
5.What is thermodynamic cycle?
A Thermodynamic cycle is a series of thermodynamic processes transfering heat and work, while varying pressure,temperature,and other state variables, eventualy returning a system to its inital state.
6.List the various thermodynamic processes:
1. Adiabatic process- a process with no heat transfer into or out of the system
2. Isochoric process- a process with no change in volume, in such case the system does no work
3. Isobaric process- a process with no change in pressure
4. Isothermal process- a process with no change in temperature
7. List the factors of power plant performance. The performance of a power plant can be expressed through some common
performance factors as
1. Heat rate
2. Capacity factor
3. Economic efficiency
4. Load factor
5. Operational efficiency
8.What are available energy sources for various power plants?
1.Conventional energy sources or Non-renewable energy sources
2. Non conventional energy sources or Renewable energy sources
