Answer: B
NEW QUESTION # 144
What is the main reason for using instrumentation in energy audits?
Answer: C
Explanation:
Instrumentation in energy audits serves multiple functions, but theprimary reasonis to determine energy flows.
* Measuring Energy Flows:
* Instrumentation helpsquantify energy usein different systems, such as electricity, HVAC, and industrial processes.
* It helps identifywhere energy is used, lost, or wasted.
* Supporting Energy Conservation Efforts:
* By measuring energy flows, auditors canidentify inefficienciesand recommend solutions.
* Other Options Analysis:
* Saving energy (A):A result of energy audits, not the main purpose.
* Validating utility bills (C):Important but secondary to understanding energy flows.
* Supporting the local economy (D):Not relevant.
Thus, the correct answer isB. Determine energy flows.
NEW QUESTION # 145
Calculate the monthly electric bill for a customer that used 400 kW and 75,000 kwh during one month. Use the following declining block structure for a monthly bill:
SELECT THE CORRECT ANSWER
Answer: B
Explanation:
We need to calculate the monthly electric bill based on the given pricing structure.
Step 1: Identify Charges from the Table
* Customer charge: $50/month
* Peak demand charge: $10/kW-month
* Electric consumption charges:
* First 25,000 kWh @ $0.06/kWh
* Excess (75,000 - 25,000) = 50,000 kWh @ $0.05/kWh
* Tax: 20% of total
