How do you calculate or choose capacitor bank?
Normal power is the multiplication of current to combination of resistive and reactive or capacitive load. From the vector sum of Apparent power minus real power we can get reactive power(KVAr), which is basically lagging power due to reactive load. This will be the exact rating of capacitor bank. You can find it by cos $ of apparent power.
What is the life expectancy of a heat pump?
It depends on how much your heat pump is used, checked, serviced, and how well it is maintained. (Always have your HVAC systems regularly maintained to increase life expectancy!) The usage of a heat pump varies greatly depending on where you live. Other factors can include if it is an air-source or ground-source. So, a very general ball park life expectancy of a heat pump is anywhere from 15-25 years for the inside components.
how long does a run capacitor last?
Start or run capacitor? How often does the motor cycle on and off? The biggest enemy of capacitors is heat. If the unit is outside in the summer heat, it's lifetime is much shorter than one inside where the temp is conditioned. So, depending on the factors above, the answer could range anywhere from as short as a year to ten years or more.
How do you take the Capacitance farads and voltage of a capacitor to determine its watt hours or amp hours?
1/(2 x 3.142 x f x C) where f is frequency of the supply & C is capacitance in farads. for example mains frequency of 50Hz and capacitor of 1uF = reactance of 3182 ohms. Watts = (volts) squared / reactance = 250 volts sq / 3182 = 19 watts then multiply by time. Other factors involved but just approximation.
How to differ from production and productivity?
Production refers to the volume, value or quantity of goods and services produced by a worker, plant, firm or economy. Its the sum total of the results achieved by the various factors together. Productivity, on the other hand, is concerned not merely with the total value or volume of output of product, what is more important is that it shows us the efficiency of the production. The difference between the two is when we find that all increases in production, does not necessairly result in increased productivity. If increase in total output is brought about with an increase in the input of factors of production, production will have increased, but productivity will only remain constant or low. Keeping all factors same, when we achieve higher output, then it is called increased productivity. Production refers to the volume, value or quantity of goods and services produced by a worker, plant, firm or economy. Its the sum total of the results achieved by the various factors together. Productivity, on the other hand, is concerned not merely with the total valur or volume of output of product, what is more important is that it shows us the efficiency of the production. The difference between the two is when we find that all increases in production, does not necessairly result in increased productivity. If increase in total output is brought about with an increase in the input of factors of production, production will have increased, but productivity will only remain constant or low. Keeping all factors same, when we achieve higher output, then it is called increased productivity. In fact Productivity refers to the quality of production. The clear definition of Productivity is the ratio of output to aggregate inputs. As per the International Labour Organization, the aggregation, if done in monetory terms, gives the exact value of productivity. A bit of common sense can tell that productivity is valued higher than one..as output should be more than all the inputs put together. However, it is not uncommon to hear the words labour productivity, material productivity etc. When such factors of production are referred with the word 'productivity', one has to understand that the evaluation of such factors with reference to production(output) is being done. In technical terms, we call them partial productivities. for example, Labour productivity means that the ratio of output to the corresponding labour input. This can be the out put achieved per man-hrs spent to get that output.
Why has life expectancy increased in the U.S. since 1900?
Life expectancy in the U.S. has increased since 1900 due to advancements in medical technology, improved public health measures, better sanitation, access to clean water, and increased awareness of healthy lifestyle choices. These factors have collectively led to a decrease in infant mortality rates and a decline in deaths from infectious diseases.
What were three reasons for population explosion?
The major factors that are responsible for population explosion are illiteracy, reduced mortality, increased birth rate, and an increase in life expectancy.
What are the factors that affect life expectancy?
culf
Is life expectancy determined at birth?
No life expectancy is not determined at birth. Life expectancy is determined by a variety of factors. Factors that influence life expectancy are quality of life, health factors, environment, location, family life among others. Exercise and eating habits influence our life expectancy, smoking and alcohol as well as illegal (and legal) drug use (abuse) can lead to a lower life expectancy. Health care and technology will generally improve throughout peoples' lives leading to an increase in life expectancy.
What is the net force of a capacitor?
This question does not make sense. For what use, or what kind, even the size are all factors of a capacitor. Look up the definition of what a capacitor is and then ask a real question.
What four factors increased industrial power?

How have the life expectancy of males and females changed over the last 100 years?
Overall, the life expectancy of both males and females has increased over the last 100 years due to advancements in healthcare, sanitation, and technology. Females tend to have a longer life expectancy than males, and this gap has narrowed but still persists. Factors like lifestyle, genetics, and access to healthcare continue to influence life expectancy for both genders.
Why has the life expectancy has increased in the last 100 years because?
The increase in life expectancy over the last 100 years can be attributed to advancements in healthcare, improved sanitation, better access to clean water, advancements in medical technologies, and increased awareness about healthy lifestyles. These factors have collectively led to a decreased prevalence of infectious diseases, better management of chronic conditions, and overall improved quality of life.
What was the life expectancy in 1967?
The average life expectancy in 1967 was around 70 years. However, life expectancy can vary depending on factors such as gender, location, and socioeconomic status.
What are the three factors that determine the charge of a capacitor?
If you mean the capacity of the capacitor then, Factors are:- Area of of overlap of the plates Separation of the plates How good is the insulating material between the plates (the dielectric) If you mean how large a charge can be stored then, Factors are:- The capacitance of the capacitor (C). The applied voltage (V). Charge Q =CxV V cannot exceed the dielectric's breakdown voltage.
Average population age in France?
The average population age in France is around 42 years old. This is due to factors such as lower birth rates and increased life expectancy contributing to an aging population.
What was the life expectancy of men in 1915?
The life expectancy for men in 1915 was around 49 years. However, life expectancy varies depending on factors such as location, social class, and access to healthcare.
