The cyclepersecond was a once common unit of frequency . With the organization of the International System of Units abbreviated SI from the French in 1960, the cyclepersecond was officially replaced by the hertz , or reciprocal second&mdash i.e. the cycle in cyclepersecond was dropped. Symbolically, cyclepersecond units are cyclesecond , while hertz is 1 second reciprocal second, without cycle or math text s 1 math . Citation needed date April 2011 Perhaps because of the convenient brevity it brings to both speech and writing, this particular mandate has been so widely adopted as to render the old cyclepersecond all but extinct. The obsolete terms kilocycle , megacycle and kilomegacycle still occur in some older documents the modern equivalents are kilohertz, megahertz and gigahertz, respectively. Criticism Nonetheless, the change is not without its critics, who argue that the hertz should be redefined as simply a renaming of the cyclepersecond it displaced, rather than as the reciprocal second Citation needed date April 2011 . Since SI has adopted the radian as its preferred but dimensionless unit of angle , but left its explicit writing discretionary in unit combinations, the radian persecond has perhaps a better claim than the cyclepersecond to being equivalent to the reciprocal second. But the hertz is overwhelmingly some would say exclusively used in the sense of cyclepersecond, and certainly never used in the sense of radian persecond.

The metre or meter persecond squared is the Units of measurement unit of acceleration in the International System of Units SI . As a SI derived unit derived unit it is composed from the SI base unit s of length, the metre , and the standard unit of time, the second . Its symbol is written in several forms as m s sup 2 sup , m s sup 2 sup , or m s sup 2 sup . As acceleration, the unit is interpreted physically as change in velocity or speed per time interval, i.e. metre persecondpersecond . Example An object experiences a constant acceleration of one metre persecond squared 1 m s sup 2 sup from a state of rest, when it achieves the speed of 5 m s after 5 seconds and 10 m s after 10 seconds. Related units Newton s Second Law states that force equals mass multiplied by acceleration. The unit of force is the newton unit newton N , and mass has the SI unit kilogram kg . One newton equals one kilogram metre persecond squared. Therefore, the unit metre persecond squared is equivalent to newton per kilogram, N kg sup 1 sup , or N kg. ref Kirk, Tim Physics for the IB Diploma Standard and Higher Level , Page 61, Oxford University Press, 2003 ref Thus, the Earth s gravitational field near ground level can be quoted as 9.8 metres persecond squared, or the equivalent 9.8 N kg.

A pulse persecond PPS is an electrical signal that very Accuracy and precision accurately repeats once persecond i.e. with a frequency of 1 Hertz . PPS signals are output by various types of precision clocks, including atomic clock s, radio clock s and some models of GPS receiver s. Depending on the source, properly operating PPS signals have an accuracy ranging from a few nanoseconds to a few milliseconds. Uses PPS signals are used for precise timekeeping and time measurement. One increasingly common use is in computer timekeeping, including the Network Time Protocol NTP protocol. Because GPS is considered a stratum disambiguation Telecoms stratum 0 source, a common use for the PPS signal is to connect it to a PC using a low latency, low jitter wire Electrical connection connection and allow a program to synchronize to it this makes the PC a stratum 1 time source. Note that because the PPS signal does not specify the time, but merely the start of a second, one must combine the PPS functionality with another time source that provides the full date and time in order to ascertain the time both accurately and precisely.

thermodynamics cTopic Processes and Cycles The Rankine cycle is a cycle that converts heat into work. The heat is supplied externally to a closed loop, which usually uses water. This cycle generates about ... cycle is the fundamental thermodynamic underpinning of the steam engine . Description File Rankine cycle layout.png thumbnail 330px Physical layout of the four main devices used in the Rankine cycle The Rankine cycle most closely describes the process by which steam operated heat engine heat engines ... fuels such as coal , natural gas , and fuel oil oil . The Rankine cycle is sometimes referred to as a practical Carnot cycle because, when an efficient turbine is used, the TS diagram begins to resemble the Carnot cycle. The main difference is that heat addition in the boiler and rejection in the condenser are Isobaric process isobaric in the Rankine cycle and Isothermal process isothermal in the theoretical Carnot cycle. A pump is used to pressurize the working fluid received from the condenser ... cycle is lost, as is most of the energy of vaporization of the working fluid in the boiler. This energy is lost to the cycle because the condensation that can take place in the turbine is limited to about 10 in order to minimize blade erosion the vaporization energy is rejected from the cycle through the condenser. But pumping the working fluid through the cycle as a liquid requires a very ... in a compressor as in the Carnot cycle . The efficiency of a Rankine cycle is usually limited ... for the working fluid, the temperature range the cycle can operate over is quite small turbine ... compared with a gas turbine is why the Rankine cycle is often used as a bottoming cycle in Combined cycle combined cycle gas turbine power stations. The working fluid in a Rankine cycle follows ... from power stations is generated by the cooling systems not from the closed loop Rankine power cycle ... fluid. While many substances could be used in the Rankine cycle, water is usually the fluid ... more details
thermodynamics cTopic Processes and Cycles This article is about the adiabatic Stirling cycle . For the idealized Stirling cycle , see the Stirling engine The Stirling cycle Stirling engine article. The Stirling cycle is a thermodynamic cycle that describes the general class of Stirling devices. This includes ... publisher L.A. Mair year 1999 isbn 0 9526417 0 4 ref The cycle is reversible, meaning that if supplied ... for cryogenic cooling. The cycle is defined as a closed cycle regenerator regenerative cycle with a gas eous working fluid. Closed cycle means the working fluid is permanently contained within the thermodynamic ... regenerator which increases the device s thermal efficiency . The cycle is the same as most other ... Stirling cycle thermodynamics Image Stirling Cycle color.png thumb A Pressure volume diagram pressure volume graph of the idealized Stirling cycle. In real applications of the Stirling cycles e.g. Stirling engines this cycle is quasi elliptical. The idealized Stirling cycle consists of four ... for use in the next cycle. li Isothermal Gas compression Compression . The compression space ... of topic The Stirling cycle is a highly advanced subject that has defied analysis by many experts for over 190 years. Highly advanced thermodynamics are required to describe the cycle. Professor Israel Urieli writes ...the various ideal cycles such as the Schmidt cycle are neither physically realizable nor representative of the Stirling cycle ref Organ, The Regenerator and the Stirling Engine ... in the Stirling cycle is judged by Jakob to rank nowiki nowiki among the most difficult and involved ... Stirling cycle Most thermodynamic textbooks use a highly simplified form of a Stirling cycle consisting of 4 processes. This is known as an ideal Stirling cycle , because it is an idealized model, and not necessarily an optimized cycle. Theoretically, the ideal cycle does have high net work output percycle. However, it is rarely used for practical reasons, in part because other cycles are simpler ... more details
