We often ask, what is the purpose of learning? Why should we study? Why did you study for CEMexam so long? As many people think that, even if one day we forget the formula for the area of a triangle, we can still live very well, but if it were not for the knowledge of learning CEM Exam and try to obtain certification, how can we have the opportunity to good to future life? So, the examination is necessary, only to get the test CEM certification, get a certificate, to prove better us, to pave the way for our future life.

NEW QUESTION # 37
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: C
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 # 38
Which of the following best describes a thermally-light building?
Answer: B
NEW QUESTION # 39
A facility has the thermal cooling load profile shown in the table below. The utility rate tariff has an on-peak time-of-use billing period that begins at 10:00 a.m. and ends at 7:00p.m. Calculate the storage capacity required for a load-shifting operating strategy, to make sure that no thermal cooling Is generated by the chiller during the on-peak utility rate period.
[Question from the previous image, which was about storage capacity for load shifting, but the table was missing]
Answer: C
NEW QUESTION # 40
A piece of equipment costs $250,000 to buy and install. The annual operating cost for the equipment is
$50,000 per year. The equipment will last 15 years. After 15 years, the equipment will have no net salvage value. The annual interest rate is 10%. What is the present value of the life-cycle cost to own and operate the equipment? Use end-of-year annual cash flow analysis.
Answer: B
NEW QUESTION # 41
The temperature in an unconditioned mechanical room is found to typically be around 23°C warmer than ambient air. If the air intake of an air compressor located in the mechanical room is routed through a nearby wall so that ambient air is fed directly to the air compressor's intake, what impact can be expected on the air compressor's energy requirement?
Answer: A
