The S9G reactor is a type of small modular reactor designed for naval applications, specifically for the United States Navy's submarines and aircraft carriers. It is part of the naval nuclear propulsion program and is utilized in the propulsion systems of Virginia-class submarines. The S9G reactor is notable for its compact design, efficiency, and advanced safety features, which contribute to the long operational life of the vessels it powers.
The miner's inch is a unit of measurement used primarily in the context of water flow and irrigation, particularly in the Western United States. It represents the flow of water through an opening or a pipeline, specifically how much water flows from a mine or irrigation ditch given a certain cross-sectional area. The term is derived from historical mining practices where water was crucial for certain mining operations.
"Pound per hour" (often abbreviated as "lb/h" or simply "lb/hr") is a unit of measurement that indicates the rate at which something is produced, processed, or consumed, specifically in pounds per hour. It is commonly used in various industries to evaluate the throughput of materials, such as in manufacturing, food processing, and chemical production. For example, if a factory produces 500 pounds of a product in one hour, its production rate would be 500 lb/h.
Standard cubic centimeters per minute (sccm or cm³/min) is a unit of measurement used to quantify the flow rate of gases. It indicates the volume of gas (in cubic centimeters) that passes through a specific point in a system per minute under standardized conditions, typically at standard temperature and pressure (STP). Standard conditions often refer to a temperature of 0 degrees Celsius (273.15 K) and a pressure of 1 atmosphere (101.325 kPa).
Standard litre per minute (SLPM or L/min) is a unit of measurement commonly used in various scientific and engineering fields to measure gas flow rates. It indicates the volume of gas flowing per minute at "standard" conditions of temperature and pressure. The "standard" conditions can vary based on context but are often considered to be at a temperature of 0 degrees Celsius (273.15 K) and a pressure of 1 atmosphere (101.325 kPa).
"Baud" is a term that refers to a unit of transmission speed in telecommunications. Specifically, it measures the number of signal changes or symbols transmitted per second. One baud corresponds to one signal change (or symbol) per second. While it was historically synonymous with bits per second (bps), modern digital communication often uses more complex encoding schemes where a single symbol can represent multiple bits (e.g., through techniques like modulation).
Becquerel (symbol: Bq) is the SI unit of radioactivity. It measures the activity of a quantity of radioactive material, specifically the number of disintegrations (or decay events) that occur in a sample per second. One becquerel is defined as one disintegration per second. The unit is named after Henri Becquerel, a French physicist who discovered radioactivity in 1896.
Counts per minute (CPM) is a measurement often used in various fields, including medical diagnostics, radiation measurement, and research to quantify the frequency of events occurring within a one-minute time interval. Here are a few examples of its applications: 1. **Medical Diagnostics**: In the context of heart rate monitoring, CPM can refer to the number of heartbeats counted in one minute. It is equivalent to beats per minute (BPM).
"Cycle per second" is a unit of frequency that describes how many cycles of a periodic event occur in one second. This term is often abbreviated as "cps." 1 cps means that one complete cycle of the event occurs in one second. However, the term "cycle per second" is somewhat outdated in modern usage, having largely been replaced by the SI unit "hertz" (Hz), where 1 Hz is equivalent to 1 cycle per second.
"Flashes per minute" generally refers to the frequency or rate at which a light, such as a strobe light or a warning light, emits flashes. This measurement is often used in various contexts, including emergency vehicle lights, photography (with flash units), and certain visual displays. For example: 1. **Emergency lights**: In emergency vehicles, lights may flash at specific rates for increased visibility. A common flash rate might be 60 flashes per minute (1 flash per second).
The term "arpent" can refer to a couple of different things, primarily relating to measurement and geography: 1. **Unit of Measurement**: An "arpent" is a traditional unit of area that has been used in France and some regions of North America, particularly in Louisiana. The exact size of an arpent can vary depending on the region, but it is generally about 0.84 acres (or approximately 0.34 hectares) in Louisiana.
A Cambodian mat, often referred to as a "krama" in the context of traditional Cambodian textiles, is a type of handwoven mat made from natural fibers, such as reeds or grass. These mats are commonly used in homes for various purposes, including sitting, sleeping, and as decorative items. The crafting of these mats is an integral part of Cambodian culture, with specific techniques and patterns that reflect the country's traditions.
A "cent" is a unit of area that is commonly used in India and some other countries, particularly for measuring land. One cent is equal to 40.4686 square meters or approximately 435.6 square feet. It is often used in real estate transactions to describe the size of a plot of land. The term is most frequently encountered in the southern states of India, where land measurements can be specified in cents, such as when buying or selling property.
A "collop" is an old unit of measurement that was historically used to describe a piece or slice of meat, specifically a small piece or portion of meat that was cut from a larger piece. The term has its roots in the culinary practices of earlier centuries, where it was commonly used in English-speaking regions. The exact size and weight of a collop can vary, but it is generally understood to imply a modest portion of meat.
A Feddan (also spelled "feddan" or "fedden") is a unit of area used primarily in Egypt and Sudan. It is traditionally used to measure land, particularly agricultural land. One feddan is approximately equal to 0.42 hectares or about 1.038 acres. The term is derived from the Arabic word "فدان," which refers to a piece of land or a plot of farmland.
The term "Gunta" can refer to different things depending on the context: 1. **Land Measurement**: In some South Asian countries, such as India and Nepal, a "gunta" (or "gunta") is a traditional unit of area measurement. It is commonly used to measure land, particularly in rural regions. One gunta is equivalent to approximately 1,089 square feet or about 0.0405 acres.
A hectad is a unit of area equal to 100 hectares or 1 square kilometer (km²). It is often used in ecological and environmental studies to describe areas of land, particularly in the context of biodiversity, land use, and conservation. The term is less commonly used than hectares or square kilometers but can be useful for representing relatively small to medium-sized areas in studies that require a specific focus on land management or ecological assessments.
"Jugerum" is a term derived from ancient Roman measurements of land area. Specifically, one jugerum is approximately equivalent to 0.25 hectares or about 0.617 acres. The term was used to quantify agricultural land and is part of a system of land measurement in antiquity. The measurement was significant in Roman times for various agricultural, taxation, and legal purposes.
The kanal is a unit of area commonly used in some South Asian countries, particularly in Pakistan and parts of India, to measure land. One kanal is equivalent to 20 marlas, where one marla is traditionally understood to be 272.25 square feet. Therefore, one kanal is approximately 5,445 square feet or about 505.857 square meters. The kanal is often used in the context of real estate and agriculture.
