What is Seliger cycle?
The Seliger cycle is a theoretical thermodynamic cycle used to model the performance of an idealized air-standard dual combustion cycle, commonly used in the study of internal combustion engines. It consists of four processes: isentropic compression, constant volume heat addition, isentropic expansion, and constant volume heat rejection. The cycle is named after Wilhelm Seliger, who first introduced it in the 1940s.
What is a Binary Vapour Cycle?
A binary vapour cycle is a representation of a mercury cycle and a steam cycle on a same scale.In this vapour cycle there is comparison between the mercury cycle and steam cycle. In mercury cycle there occurs isothermal expansion of saturated water from boiler into dry saturated steam followed by isentropic expansion followed by condensation of steam and at last heating of steam and thus mercury has completed the cycle in 4 way process. In steam cycle first ther is isothermal expansion which results in converting of saturated water into dry saturated steam followed by superheated process where the steam is superheated followed by isentropic expansion of superheated steam followed by condensation of exhaust steam and at last heating of steam thus completing the cycle.
Which processes of the water cycle show heat being added and which ones show heat beign removed?
How the water cycle and heat are related: Adding or subtracting heat makes the water cycle work. If heat is added to ice, it melts. If heat is added to water, it evaporates. Evaporation turns liquid water into a gas called water vapour. As water goes through its cycle, it can be a solid (ice), a liquid (water), or a gas (water vapour). Ice can change to become water or water vapour. Water can change to become ice or water vapour. Water vapour can change to become ice or water. If heat is taken away from water vapour, it condenses. Condensation turns water vapour into a liquid. If heat is taken away from liquid water, it freezes to become ice. The water cycle involves the sun heating the Earth's surface water and resulting in the surface water evaporating. The water vapour rises into the Earth's atmosphere. The water cools and condenses into liquid droplets. The droplets grow until they are heavy and fall to the earth as precipitation (which can be rain, freezing rain or snow).
How does water work in water cycle?
in lakes rivers sea and all they will evaprate and go and change into water vapour and come down as rain from the clouds and how you pedel in the cycle it will be going on like how you pedel in the cycle this is called water cycle
Where in the water cycle does water vapor gain energy?
Water gains energy in evaporation to become water vapour.
Why coefficient of performance of absorption cycle is less than compression cycle?
In case of vapour compression cycle (VCC) the COP is given by (desired effect / work input). in the other words it can be defines as what we want and what we are paying for that... so in VCC the paying amount is very less as due to low temperature difference that why its value is more than 1. but in case of vapour absorption system the COP is given by (heat taken by evaporator/ heat given to generator). the heat input taken by evaporator is less as compared to heat given to generator.. that why its COP is less than 1......

Water vapour forms clouds and returns to earth?
The water cycle.
Is a cloud a vapour?
yes, they are condensed water. See the water cycle!
How do you improve the performance of vapor compressor refrigeration cycle?
In practical applications, vapor-compression refrigeration systems are the most commonly used refrigeration systems, and each system employs a compressor. In a basic vapor compression refrigeration cycle as shown in Figure 3.28, four major thermal processes take place as follows: • evaporation, • compression, • condensation, and • expansion.
What is compression on 4 cycle crafstman weedwacker?
Compression in a 4-cycle Craftsman weedwacker refers to the pressure created within the engine's cylinder during the compression stroke. This pressure is essential for efficient combustion, as it helps to ensure that the fuel-air mixture ignites properly, leading to optimal engine performance. Low compression can result from wear, damaged components, or incorrect assembly, leading to poor starting, reduced power, or engine stalling. Regular maintenance and checks can help maintain proper compression levels.
What is mean of compression ratio in otto cycle?
The compression ratio in an Otto cycle is the ratio of the maximum volume of the combustion chamber (when the piston is at the bottom of its stroke) to the minimum volume (when the piston is at the top of its stroke). It is a critical parameter that influences the thermal efficiency and performance of the engine; higher compression ratios typically lead to better efficiency and power output, but can also increase the risk of engine knock. In general, the compression ratio is represented as (CR = \frac{V_{max}}{V_{min}}).
What type of cycle used in refrigeration?
Refrigeration systems primarily use the vapor-compression cycle. This cycle involves the compression of refrigerant gas, which is then condensed into a liquid, allowing it to absorb heat from the environment as it evaporates back into a gas. The cycle consists of four main stages: compression, condensation, expansion, and evaporation. Alternatively, some systems may use the absorption cycle, which relies on heat to drive the refrigeration process instead of mechanical compression.
What is formed by vapour after evaporation?
More water. Look up the water cycle.
