Answer:
0.8 kilograms of fuel are consumed each second.
Explanation:
As turbines are steady-state devices, the thermal efficiency of a turbine is equal to the percentage of the ratio of the output power to fluid power, that is:

The fluid power is:



Which means that gas turbine consumes 40 megajoules of fluid energy each second, which is heated and pressurized with help of the fuel, whose amount of consumption per second is:


0.8 kilograms of fuel are consumed each second.
Answer:
Explanation:
A smaller clearance volume means a higher compression. A higher compression means better thermal efficiency. However a compression ratio too high might be troublesome, as it can cause accidental ignition of the fuel-air mix. This is the reason why Otto cycle engines have lower compressions that Diesel engines. In a Diesel engine the mix ignites by compression instead of a spark.
Answer:

Option c)
Explanation:
a.The carbon content of eutectoid steel, which is an carbon- iron alloy, is in between 0.80-0.83%
b. In hypoeutectoid steel, the carbon composition is less than 0.80% and is approximately 0.76%
c. In hypereutectoid steel, the carbon composition ranges from 0.80% - 2.0%
d. In wrought iron, the iron composition is quite low about 0.08%
