An aircraft is climbing and accelerating to reach the cruise mach number of 0.75. If aircraft is accelerating from 0.1M then, what will be the mission segment fuel fraction for this mission?

An aircraft is climbing and accelerating to reach the cruise mach number of 0.75. If aircraft is accelerating from 0.1M then, what will be the mission segment fuel fraction for this mission? Correct Answer 0.9821

Given, after acceleration mach number = 0.75 For given subsonic mission segment fuel fraction, = 1.0065 – 0.0325M = 1.0065 – 0.0325*0.75 = 0.9821.

Across the normal shockwave: 1) Stagnation pressure decreases whereas stagnation temperature remains constant 2) Mach number before the shockwave is always greater than one and after the shockwave, the Mach number need not be less than one 3) Across the shockwave there is a rise in pressure and temperature 4) The product of Mach number downstream of normal shockwave and upstream of normal shockwaves always one Which of the above statements are correct?
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:
