What is the value of ‘n’ exponential in the fuel flow law for a high bypass ratio turbofan?

What is the value of ‘n’ exponential in the fuel flow law for a high bypass ratio turbofan? Correct Answer 0.6

The value of ‘n’ exponential in the fuel flow law for a high bypass ratio turbofan is 0.6. The value of ‘n’ exponential is directly proportional to the engine bypass ratio i.e. it increases when the bypass ratio increases.

A solid-oxide fuel cell is fed with carbon monoxide and reacts with air to produce CO2. This reaction will produce 2 electrons which are used to power an electric circuit external to the fuel cell. The reaction equation is shown below: 2CO(g) + O2(g) -> 2CO2(g) ΔHr° = -565.96 kJ/mol This reaction does not occur for other types of fuel cells which use a catalyst, such as polymerelectrolyte membrane or phosphoric-acid fuel cells. The presence of carbon monoxide on the anode side of these types of fuel cells will cause catalyst poisoning, reducing the efficiency and voltage of the fuel cell. Determine the rate of enthalpy change for a carbon dioxide production rate of 208 mol/hr. The extent of the reaction occurring in the fuel cell can be obtained by the following equation: where:
The pie chart given below shows the fuel consumption by five vehicles V1, V2, V3, V4 and V5. In a month total fuel consumption by all five vehicles is 720 litre. Fuel consumption of a particular vehicle is shown in terms of degree with respect to the total fuel consumption by all these five vehicles. J1 = Difference between the fuel consumption of V4 and V5. J2 = Difference between the fuel consumption of V1 and V2. What is the value of J2 – J1?

In the question below, are given a statement followed by three courses of actions numbered I, II and III. On the basis of the information given, you have to assume everything in the statement to be true, and then decide which of the following suggested courses of actions logically follow(s) for pursuing. Statement: High-sulphur fuel oil (HSFO), essentially the leftovers of an oil refiner's output, will still flow from refineries around the world even after new rules start up in 2020 curtailing its use in the global shipping fleet.Sixty percent of the 33 refineries in a global survey will still produce HSFO in 2020 although the supply will tighten as 70 percent of these refiners plan to reduce their output.  Courses of action: I. Starting that year, ships will use marine fuel, which primarily consists of residual fuel oil, with a maximum sulphur content of 0.5 percent under International Maritime Organization (IMO) rules to reduce air pollution.  II. Currently, the global shipping fleet, which includes oil and chemical tankers as well as container ships, uses as much as 3.3 million barrels per day of HSFO with a maximum of 3.5 percent sulphur.  III. Refiners will have little incentive to produce HSFO after the regulations though some demand will remain as a small but growing number of vessels are fitted with smokestack scrubbers that remove the sulphur from the exhaust fumes and power plants will continue to consume the fuel.
