capacity

Examples of capacity in the following topics:

• Adjusting Capacity

  • Capacity adjustment takes into account maximum production levels and the alteration of this level depending on how the firm wants to grow.
  • Capacity planning is the process of determining the production capacity needed by an organization to meet changing demands for its products.
  • In the context of capacity planning, "design capacity" is the maximum amount of work that an organization is capable of completing in a given period.
  • Capacity utilization is a concept in economics and managerial accounting that refers to the extent to which an enterprise or a nation actually uses its installed productive capacity.
  • Adjusting capacity will affect the amount of items produced on the assembly line.

• Capacity Planning

  • Capacity planning revolves around answering the question "How much?
  • When making capacity decisions, managers must answer the simple question, "How much?"
  • Long-term capacity decisions involve facilities and major equipment investments .
  • Capacity decisions are also required in short-term situations.
  • The question managers must answer for capacity decisions is simply "How much?"

• Specific Heat and Heat Capacity

  • the molar heat capacity, which is the heat capacity per mole of a pure substance.
  • Molar heat capacity is often designated CP, to denote heat capacity under constant pressure conditions, as well as CV, to denote heat capacity under constant volume conditions.
  • Units of molar heat capacity are $\frac{J}{K\bullet mol}$.
  • the specific heat capacity, often simply called specific heat, which is the heat capacity per unit mass of a pure substance.
  • The molar heat capacity of water, CP, is 75.2 $\frac{J}{mol\bullet K}$.

• Water’s High Heat Capacity

  • The high heat capacity of water has many uses.
  • The water then remains hot for a long time due to its high heat capacity.
  • Water's high heat capacity is a property caused by hydrogen bonding among water molecules.
  • Water has the highest specific heat capacity of any liquid.
  • In fact, the specific heat capacity of water is about five times more than that of sand.

• Capacity decisions

  • The question managers must answer for the capacity decision area is the same as the question for inventory: "How much?
  • " Determining the organization's capacity to produce goods and services involves both long-term and short-term decisions.
  • Long-term capacity decisions involve facilities and major equipment investments.
  • A large single airplane like the Super Jumbo may not be the right capacity decision for an airline that serves numerous medium sized cities.
  • Capacity decisions also involve short-term situations.

• Lung Volumes and Capacities

  • Different animals exhibit different lung capacities based on their activities.
  • At maximal capacity, an average lung can hold almost six liters of air; however, lungs do not usually operate at maximal capacity.
  • Air in the lungs is measured in terms of lung volumes and lung capacities .
  • The lung capacities are measurements of two or more volumes.
  • The total lung capacity of the adult male is six liters.

• Lung Capacity and Volume

  • Lung volumes and capacities refer to phases of the respiratory cycle; lung volumes are directly measured while capacities are inferred.
  • The two most often used measurements are FVC (forced vital capacity) and FEV1 (forced expiratory volume in one second).
  • Vital Capacity (VC) is the maximum amount of air that a person can exhale after inhaling as much air as possible.
  • Other important lung volumes related to lung capacity are residual volume (RV) and total lung capacity (TLC).
  • The most widely used diagnostic application for lung capacities is the ratio between forced expiratory volume (FEV1) and forced vital capacity (FVC).

• Heat Capacity

  • In SI units, heat capacity is expressed in units of joules per kelvin (J/K).
  • Heat capacity is an extensive property, so it scales with the size of the system.
  • The heat capacity of most systems is not a constant.
  • This defines the heat capacity at constant volume, CV.
  • Another useful quantity is the heat capacity at constant pressure, CP.

• Logistic Population Growth

  • The formula we use to calculate logistic growth adds the carrying capacity as a moderating force in the growth rate.
  • Thus, population growth is greatly slowed in large populations by the carrying capacity K.
  • In addition, the accumulation of waste products can reduce an environment's carrying capacity.
  • In both examples, the population size exceeds the carrying capacity for short periods of time and then falls below the carrying capacity afterwards.
  • This fluctuation in population size continues to occur as the population oscillates around its carrying capacity.

• Specific Heat for an Ideal Gas at Constant Pressure and Volume

  • An ideal gas has different specific heat capacities under constant volume or constant pressure conditions.
  • The heat capacity at constant volume of nR = 1 J·K−1 of any gas, including an ideal gas is:
  • The heat capacity at constant pressure of 1 J·K−1 ideal gas is:
  • Measuring the heat capacity at constant volume can be prohibitively difficult for liquids and solids.
  • The heat capacity ratio or adiabatic index is the ratio of the heat capacity at constant pressure to heat capacity at constant volume.
