Advantages of Gas Turbine engine
1. They are small in size, weigh less and have low initial cost per unit output.
2. They are easy to install within short periods.
3. They are quick-starting and smooth running.
4. They offer flexibility by supplying electricity for power generation as well as by supplying compressed air for process needs.
5. They are capable of using a range of liquid and gaseous fuels including synthetic fuels.
6. They are subjected (put) to fewer environmental restrictions than other prime movers.
7. Water consumption is less compared to steam power plant.
Disadvantages
1. An electric motor or an I.C. engine is necessary for starting the plant. The starting motor must bring the compressor well towards the operating speed. So, starting is not simple as in the case of other power plants.
2. Gas turbine plants have less vibrations when compared with reciprocating engines of the same speed. However the high frequency noise from the compressor is objectionable.
3. High temperatures impose severe restriction on the servicing conditions of the plant.
4. Overall efficiency is low since two-thirds of the total power output is used for driving the compressor.
5. The blades of the turbine require special cooling methods due to the severity of operating temperatures and pressures. In practice, the temperatures at the entry of the turbine are as high as 1100°C - 1260°C. Hence they should be made of special metals and alloys.
6. They are incompatible with solid fuels.
Answer: Yes, it will be around 40ppm(at steady state)
Explanation:
The above question can be solved by performing material balance of CO in the building. The material balance equation is given by, Rate of change of CO in the building = Rate of inflow of CO into the building - Rate of outflow of CO from the blood
Answer:
Accuracy basically refers to closeness between the measured value to the actual and standard value is known as accuracy. In the mathematics and engineering the accuracy basically tells that the nearest measurement value with reference to the actual true value.
According to the International organization of standardization (ISO), the accuracy referring to the consistent and true results.
Precision basically refers to the value whose results is consistent when the measurement are repeated more than two times. Precision value may be different from one another because of the occurrence of random error in the form of the observational error.
Explanation:
Utilising the principles of a circular economy and making sure the products they purchase are not manufactured in a way that adversely affects the environment.
