Are the types of air craft gas turbines?

Types of Gas Turbine Engines (Jet Engines)

• Turbojet. A turbojet is the simplest of all aircraft turbine engines, consisting of four sections: compressor, combustion chamber, turbine section and exhaust.
• Turboprop.
• Turbofan.
• Afterburning Turbojet.

What is the main challenge in the development of gas turbine?

Environmental challenges with gas turbines include low levels of NOx, CO and soot amongst other pollutants. Specifically, ultra-low NOx combustor technology is required to meet the ozone depletion challenge. Researchers are facing concerns about the development of dry low-NOx stationary and aero engines.

Which of the following plant is expected to have the longest expected life?

Power plant is expected to have the longest life.

Which of the following plant has maximum efficiency?

Hydropower Plant

What is a good diversity factor?

Usually, the maximum demands of the consumers do not occur at the same time. The diversity factor can be equal or greater than 1. If the value of the diversity factor is greater than 1, then it is a good diversity factor, and 1.0 represents a poor diversity factor.

How can diversity factor be improved?

A high diversity factor could be obtained by:

1. Giving incentives to farmers and/or some industries to use electricity in the night or light load periods.
2. Using day-light saving as in many other countries.
3. Staggering the office timings.
4. Having different time zones in the country like USA, Australia, etc.

What is diversity factor in HVAC?

Diversity is defined as the probability that an internal gain will be active at the time of peak building load. An ASHRAE research project on office buildings noted diversity factors for lighting ranging from 70 to 85% and for receptacles between 42 to 89%.

What is meant by diversity factor?

In the context of electricity, the diversity factor (or simultaneity factor. ) is the ratio of the sum of the individual non-coincident maximum loads of various subdivisions of the system to the maximum demand of the complete system. The diversity factor is always greater than 1.

Which one of the following is the load factor?

Explanation: Load factor is the ratio of average demand to the maximum demand. Average demand can not be greater than maximum demand. So the value of load factor is always less than unity.
