Most motors must be derated for altitude.The following chart gives typical horsepower derating factors, but the derating factor should be checked for each motor.A 50 hp motor operated at 6000 feet, for example, would be derated to 47 hp, providing the 40c ambient rating is still required.Altitude deratring factor 3300-5000 0.97 5001-6600 0.94.

The equations in table 1 right for determining weight correction factor for specific installations are based on the inside diameter of the raceway and the outside diameter of the conductor.When you have three single conductors of equal diameter and weight which is the most common scenario, you can expect a higher weight factor for the cradle position than the triangular position.
Data, it is important to consider the differentiators and variables unique to the project and factor them accordingly.All projects are unique and have some variables.Even those with the exact same design will have some differentiators, including design or capacity varying site conditions such as soil, drainage, and so on.

Correction factor given in table 3.For example, assume a sensor calibrated for nitrogen is being used to sense nitrous oxide, and the sensor is outputting a value of 20 slpm of nitrogen.Multiplying 20 slpm by the nitrous oxide correction factor of 0.7 gives an actual flow of 14 slpm of nitrous oxide.Table 3.
The correction for pressure drop is shown in figure 7 and can be calculated from equation 5.As indicated, a higher pressure drop would result in a finer separation and lower pressure drop in a coarser separation.C 2 3.27 x 25 of the cyclone diameter to a maximum-0.28 eq.5 where c 2 correction for influence of pressure drop.Pressure.
Figure 6.1 variation of temperature correction factor, k t , with temperature.K t is a multiplying factor that will increase the calculated value of belt tensions to allow for the increased resistances that can be expected due to low temperatures.Fig-ure 6.1 provides values for factor k t.W m q 2,000 60 v-----33.33 q v.
Power factor correction requirements at the steel mill were determined through field measurements via testing and computer analysis with the help of power factor and harmonic software.Using portable harmonic monitoring instruments, on-site measurements were performed at the main switchgear feeder circuit breaker locations on the 13.8kv system.
A constant tension fuzzy control system is designed for four-roller cold rolling mill to ensure that strap steel tension is constant.
