advantages of liquid rocket fuels over solid fuels

Hydrogen has a high calorific value, and as such, is an ideal fuel. It has a high calorific value. It is also 100% pollution free, as the only product formed on combustion is water vapour. Many gaseous fuels such as, water gas, coal gas, etc. contain comparatively high percenta..

Liquid and gaseous fuels form explosive mixtures making them difficult to handle. Since they require special leak proof containers their storage is difficult. They are expensive compared to solid fuels..

Fuels come in many varieties such as wood, cow dung, charcoal, kerosine and Liquified Petroleum Gas (LPG). These are used for cooking purposes. Coal, fuel, oil and natural gas are used in industries. Petrol and diesel are used in automobiles and locomotives. Specially prepared ..

Petroleum is a dark, viscous, foul smelling liquid, a mixture of solid, liquid and gaseous hydrocarbons with traces of salt, rock particles and wat..

Rocket Propellants - Propellants are the fuels used in rockets for propulsion. For example, alcohol, liquid hydrogen, liquid ammonia, kerosene, hydrazine and paraffin can be used as propellants. To burn them, rocket fuels require..

The fuel used in a nuclear reactor is enriched U-235. The solid fuel is made into pellets or rods which are shielded by placing it in stainless steel tubes. Note : Enrichment is a process by which the percentage of fissionable U-235 is increased and is the process..

The motion of a rocket is an application of Newton's third law of motion. A jet of hot gases is forced downwards (action) thereby pushing the rocket upward (reaction). Let the mass of the rocket be m at time t. Let a mass D m of gas be ejected from the rock..

The speed acquired by the rocket when the whole of the fuel gets burnt is called the burn-out speed of the rocket. It is the maximum speed acquired by the rocket. When the rocket acquires burn-out speed vb, the mass of the rocket becomes ..

Water is the most common liquid. Density of water at 4 o C is 1 g cm - 3 (1000 kg m - 3 ). Example : 28 kg of fuel completely fills a 40 liter petrol tank of a vehicle. What is the density of the fuel? (1 liter = 10 - 3 m 3 ) Suggested Answer : Mass o..
