NEW QUESTION # 66
If outside air has a temperature of 30°C dry bulb and 20°C wet bulb, what is the dew point temperature?
Answer: C
NEW QUESTION # 67
A facility has a monthly peak power demand of 1,000 kW and an average power factor of 80%. The facility pays a demand charge of $7.50/kVA-month. What is the additional cost per month because the power factor is less than 100%?
Answer: C
Explanation:
To calculate the additional cost due to a power factor of less than 100%, follow these steps:
Step 1: Convert Real Power (kW) to Apparent Power (kVA)
Step 2: Compute Additional kVA Due to Power Factor
NEW QUESTION # 68
If the temperature difference across an external wall is 20°C and the heat flow across the wall is 2.5 Watts/m², calculate the insulation value of the wall (including inside and outside air films)?
Answer: C
NEW QUESTION # 69
Thermal scans of electrical equipment are useful for:
Answer: A
Explanation:
Step 1: Purpose of Thermal Scans
Thermal scans (infrared thermography) detecttemperature variationsin electrical components.
* Loose connectionsincrease resistance # causeoverheating, which isvisible in thermal scans.
Step 2: Analysis of Each Option
* A. Locating areas of high power factor#Incorrect#Power factor is measured with power meters.
* B. Reading current-carrying capacity of conductors#Incorrect#Measured using ammeters and engineering data.
* C. Locating a loose electrical connection#Correct#Loose connections causeheat buildup, easily detected with thermal scans.
* D. Measuring the load on a refrigerant system#Incorrect#Refrigerant loads are measured using pressure sensors and flow meters.
Thus, the correct answer isC. Locating a loose electrical connection.
