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?
Study the given pie-chart and answer the question that follows. The pie-chart represents the consumption of fuel (in million litres) by various modes of transport of a country X in the year 2015. The total consumption of fuel by various modes of transport of the country is 800 million litres. (The data shown here is only for mathematical exercise. They do not represent the actual figures of the country.) The fuel consumed by light vehicles is approximately what percentage of the combined consumption of fuel for aviation and waterways?
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:
With reference to 'fuel cells' in which hydrogen-rich fuel and oxygen are used to generate electricity, consider the following statements: 1. If pure hydrogen is used as a fuel, the fuel cell emits heat and water as by-products. 2. Fuel cells can be used for powering buildings and not for small devices like laptop computers. 3. Fuel cells produce electricity in the form of Alternating Current (AC) Which of the statements given above is/are correct?
