Answer: C
NEW QUESTION # 136
In a warehouse, lights are mounted 4 meters above the floor. This provides an average light level of 150 lux.
To increase the light level without installing more lights or higher Wattage lights, you lower the light fixtures with pendants so that the lights are located 3.25 meters above the floor. Calculate the new average light level on the floor.
Answer: B
NEW QUESTION # 137
In a typical compressed air system, energy can be saved by which of the following actions?
Answer: E
NEW QUESTION # 138
Electricity costs SO. 10 per kWh. if an electric water heater has an efficiency of 95*6. what is the equivalent price of natural gas per Gigajoule for a natural gas water heater? The natural gas water heater has an efficiency of 95*t based on lower-heating value.
[Natural gas has an energy content of 36.400 K|/m3 (higher-heating value) and 32-760 K/m3 (lower-heating value).] SELECT THE CORRECT ANSWER
Answer: D
Explanation:
To determine the equivalent price of natural gas per gigajoule (GJ) for a natural gas water heater, we compare the cost of electricity and natural gas on an energy-equivalent basis.
Step 1: Convert Electricity Cost to Cost per GJ
* Electricity cost:$0.10/kWh
* 1 GJ =277.8 kWh
