In the load calculations stipulated in Article 220 of the National Electrical Code, branch circuits must not be undersized for safety purposes. In industrial applications, there are always 'rule of thumbs'. The exact calculations are a product of ideal conditions. But in reality, there are heat losses through the conductor materials. Therefore, it is mandatory that a safety factor should be incorporated. For the calculation of the neutral load, it is a rule of thumb to apply a demand factor of 70% for household electrical appliances like the oven, dryers and cooking ranges. Therefore, the minimum neutral demand load for this range is 25 kW * 0.7 = 17.5 kW.

Answer:
hello the answer is 47m/s
Answer:
Explanation:
I'm going to assume that all the givens are in m/s. If I am correct, The orange line is speeding up. It is going from 4 m/s to 7 m/s. Its slant is from lower left to upper right. It is increasing in speed.
The green line is slowing down. It is going from 4 to 0 m/s. It's slant is from upper left to lower right.
The blue line is horizontal. It is neither slowing down or speeding up.
Answer:
Gay Lussac law
Explanation:
Gay Lussac law states that for a gas kept at constant volume (so, in a rigid container), the pressure of the gas is directly proportional to the absolute temperature.
In mathematical formula:
where
p is the gas pressure
T is the absolute temperature
According to this law, we see therefore that if the absolute temperature of the gas is doubled:
T' = 2T
The pressure will also double:
