NEW QUESTION # 115
A new energy-efficient boiler costs $60,890 to buy and install. The new energy-efficient boiler will save
$15,400 per year and last for 20 years. What is the internal rate of return (IRR) of the project?
Answer: A
NEW QUESTION # 116
A 100-kW electrical load has a power factor of 75%. What capacitance, in KVAR, will improve the power factor to 95%?
Answer: C
NEW QUESTION # 117
Natural gas costs $4.80/GJ. How much does it cost to heat 500 liters of water from 18°C to 50°C using a natural gas water heater with an efficiency of 85%? [The efficiency and fuel price are both based on HHV.
The specific heat of water (C) is 4.2 kJ/kg-°C.]
Answer: A
Explanation:
To calculate the cost of heating water using natural gas:
Step 1: Compute Energy Required to Heat the Water
Given:
* Mass of water = 500 L = 500 kg
* Temperature rise (#T) = 50°C - 18°C = 32°C
* Specific heat of water (Cp) = 4.2 kJ/kg-°C
Energy Required (Q)=m×Cp×#T
=500×4.2×32
=67,200 kJ=67.2 MJ
NEW QUESTION # 118
An air-conditioning system at full load is rated at 70-kW (thermal cooling) and has a coefficient of performance (COP) of 4.1. What is the electrical load at full load?
Answer: E
NEW QUESTION # 119
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: D
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
