The ocean plays a key role in the water cycle as it is the source of 86% of global evaporation. [2] The water cycle involves the exchange of energy, which leads to temperature changes. When water evaporates, it takes up energy from its surroundings and cools the environment. When it condenses, it releases energy and warms the environment.
In thermodynamics, a temperature–entropy (T–s) diagram is a thermodynamic diagram used to visualize changes to temperature (T ) and specific entropy (s) during a thermodynamic process or cycle as the graph of a curve. It is a useful and common tool, particularly because it helps to visualize the heat transfer during a process.
The saturated liquid curve is the curve separating the subcooled liquid state and the two-phase state in the T–s diagram. [1] When used in a power cycle, the fluid expansion depends strongly on the nature of this saturation curve: A "wet" fluid shows a negative saturation vapor curve.
T–s (entropy vs. temperature) diagram of an isentropic process, which is a vertical line segment The entropy of a given mass does not change during a process that is internally reversible and adiabatic.
Thermodynamic diagrams are diagrams used to represent the thermodynamic states of a material (typically fluid) and the consequences of manipulating this material. For instance, a temperature– entropy diagram ( T–s diagram ) may be used to demonstrate the behavior of a fluid as it is changed by a compressor.
The water vapor with condensed droplets often seen billowing from power stations is created by the cooling systems (not directly from the closed-loop Rankine power cycle). This "exhaust" heat is represented by the "Q out" flowing out of the lower side of the cycle shown in the T–s diagram below.
It's 300 miles long from the north to the south, and from east to west, it's 118 miles wide, and wind over water creates dangerous currents. So it's the winds that are creating the dangerous ...
T-S diagram of a station in the North Pacific. In oceanography, temperature-salinity diagrams, sometimes called T-S diagrams, are used to identify water masses.In a T-S diagram, rather than plotting each water property as a separate "profile," with pressure or depth as the vertical coordinate, potential temperature (on the vertical axis) is plotted versus salinity (on the horizontal axis).
