Does mass affect tidal force?
The tidal force is proportional to the mass of body causing it and to the radius of the body subjected to it.
What force causes tides to change?
Gravity is one major force that creates tides. In 1687, Sir Isaac Newton explained that ocean tides result from the gravitational attraction of the sun and moon on the oceans of the earth (Sumich, J.L., 1996).
What would be the effect on the Earth tides if the moon had a greater mass?
(Each lunar revolution takes about 29.5 days). If the moon were half its mass, then the ocean tides would have been correspondingly smaller and imparted less energy to it.
What force is mostly responsible for tides it is the gravity that comes from?
The Moon’s gravity is mostly responsible for our tides, but the Sun also plays a role (Figure 14.13). The Sun is much larger than our Moon. It has a mass about 27,500,000 times greater than the Moon. A very large object like the Sun would produce tremendous tides if it were as near to Earth as the Moon.
Which two main points are necessary for its working OTEC?
Answer: OTEC uses the ocean’s warm surface water with a temperature of around 25°C (77°F) to vaporize a working fluid, which has a low-boiling point, such as ammonia. That condenses the working fluid back into a liquid, so it can be reused.
What does OTEC stand for *?
Ocean Thermal Energy Conversion (OTEC) is a unique source of renewable energy that provides stable power, 24 hours a day, 365 days a year, and does not require energy storage systems.
What does Otace stand for?
OTACE
| Acronym | Definition |
|---|---|
| OTACE | On Time and Above Client Expectations (Capgemini; Paris, France) |
| OTACE | On Time and Above Customer Expectation |
What does GJ stand for?
GJ means “Good Job”
What is the basic principle of OTEC?
The working principle of an OTEC plant is that it uses the warm water to heat and vaporize a liquid ( working fluid). And this working fluid develops pressure which forces it to evaporate.
How efficient is OTEC?
The overall efficiency of a multi-megawatt-sized OTEC electrical power plant, all inclusive from seawater to net electric power, is typically around 2%. OTEC has enormous potential as a source of clean, renewable, and base-load electricity for many nations, territories and states near tropical waters.
What are the different types of OTEC?
There are three types of OTEC systems: closed-cycle, open-cycle, and hybrid. Closed-cycle systems use the warm water at the ocean’s surface to vaporise a working fluid with a low-boiling point such as ammonia. The expanding vapour rotates a turbine.
Which is the working fluid in open cycle?
Which is the working fluid in open cycle? Explanation: In the open/Claude cycle, water is the working fluid. The warm water surface water is caused to boil by lowering the pressure, without supplying any additional heat.
How many types of OTEC plants are there a 1 B 2 C 3 D 4?
6. How many types of OTEC plants are there? Explanation: There are three types of ocean thermal energy plants. They are closed cycle systems, open cycle ocean thermal energy conversion and hybrid ocean thermal energy conversion.
Which is the working fluid in open cycle OTEC?
centred their attention on an open-cycle OTEC system that employs water vapour as the working fluid and dispenses with the use of a refrigerant. In this kind of system, warm surface seawater is partially vaporized as it is injected into a near vacuum.
