Explanation:
Resistive losses in the stator and rotor are proportional to the square of the current through them multiplied by their resistance. When the load and current are at their maximum, this type of loss occurs most frequently in an AC motor.
Explanation:
A mechanical pressure measurement tool is called a Bourdon gauge. To gauge the pressure in steam or hot water pipes, they are frequently installed in boiler systems.
Explanation:
The Coefficient of Utilization is not affected by the type of lamp (Cu). The contribution of lamp light to the useful light at the work surface is measured by the coefficient of utilization or Cu. Useful light is lost when it is reflected in the wrong direction or gets trapped in the luminaire. It is also lost when a space has dark surfaces because they do not reflect light as well as surfaces that are lighter in color.
Explanation:
Greywater is produced by sinks, showers, washers, and possibly dishwashers (dark greywater). The majority of the time, rainwater is collected and used for non-potable purposes, but with the right treatment, it can also take the place of potable water.
Explanation:
A Level 1 energy audit is frequently the first step in determining the scope of later, more in-depth audits. The energy auditor will quickly scan a building to grasp its fundamental systems and operation before making recommendations for low- and no-cost upgrades as well as for more in-depth studies that are likely to be of sufficient value to the building's owner or occupant.
Explanation:
Chemical smoke can be used to find sources of air infiltration through the building fabric and to determine HVAC air flow patterns.
Explanation:
Inductive loads cause a lagging current by increasing the reactive power necessary to create the magnetizing field necessary for their operation. Capacitor banks draw a current that follows the voltage and can reduce the overall amount of reactive power required.
