Answer:

D. Inspecting the muffler

Explanation:

HVAC/refigeration systems are sealed systems that use refrigerant not combustion. A muffler is found on combustion systems.

You would disconnect, flush, seal, and possibly replace the condenser if the condenser is found to be failing.

Answer:

C. Replacing the condenser is least likely a step in replacing a failed compressor.

Explanation:

To answer the above question, we need to understand the work of Air-cooling systems. There are 2 main units, compressor and condenser. Compresser and condenser are connected by the airtight pipe, and the required gas is injected in the system.

Compressor compresses the gas, compresed gas moves to condenser, condenser cools the gas, and the gas is expanded again, and then heat transfer takes place in indoor unit. Again the compressor compresses the gas, and process goes on.

So here, compressor is failed, so we need to inspect the muffler first of all to detect the issue, and definitely we need to remove all the gas from the system which means flushing the system, also hoses and other valves needs to be disconnected. However, replacing the condenser doesn't seems to be required to replace the failed compressor, as both are totally different units.

John has an exhaust leak in his Acura Integra GS-R, What steps would he take to fix the leak in time for his inspection?

SCORPION-xisa [38]

Answer:

Explanation:

Fist you need to identify where the leak is coming from. You can do this by either listening for the leak or spraying soapy water on the exhaust to look for air bubbles coming out of the exhaust. Depending on the spot of the leak there are many ways you can fix this leak.

1. Exhaust clamp

2. Exhaust putty

3. Exhaust tape

4. New exhaust

Exhaust clamp is best used for holes on straight pipes.

Putty is best used on welds or small holes like on exhaust manifolds or welds connecting various pieces like catalytic converters, mufflers, or resonators.

Tape will work best on straight pipes with holes.

New exhaust is for when the thig is beyond repair, like rust.

Now good luck because working on exhausts is a pain.

Alex17521 [72]

Answer:

Answer is explained in the explanation section below.

Explanation:

Solution:

Note: This question is incomplete and lacks necessary data to solve. But I have found the similar question on the internet. So, I will be using the data from that question to solve this question for the sack of concept and understanding.

Data Given:

x = 27 , 44 , 32 , 47, 23 , 40, 34, 52

y = 30, 19, 24, 13 , 29, 19, 21, 14

It is given that,

∑x = 299

∑y = 167

∑ $x^{2}$ = 11887

∑ $y^{2}$ = 3773

We are asked to verify the above values manually in this question.

So,

1. ∑x = 299

Let's verify it:

∑x = 27 + 44 + 32 + 47 + 23 + 40 + 34 + 52

∑x = 299

Yes, it is equal to the given value. Hence, verified.

2. ∑y = 167

Let's verify it:

∑y = 30 + 19 + 24 + 13 + 29 + 19 + 21 + 14

∑y = 169

No, it is not equal to the given value.

3. ∑ $x^{2}$ = 11887

Let's verify it:

For this to find, first we need to square all the value of x individually and then add them together to verify.

∑ $x^{2}$ = $27^{2}$ + $44^{2}$ + $32^{2}$ + $47^{2}$ + $23^{2}$ + $40^{2}$ + $34^{2}$ + $52^{2}$

∑ $x^{2}$ = 11,887

Yes, it is equal to the given value. Hence, verified.

4. ∑ $y^{2}$ = 3773

Let's verify it:

Again, for this we need to find the squares of all the y values and then add them together to verify it.

∑ $y^{2}$ = $30^{2}$ + $19^{2}$ + $24^{2}$ + $13^{2}$ + $29^{2}$ + $19^{2}$ + $21^{2}$ + $14^{2}$

∑ $y^{2}$ = 3,845

No, it is not equal to the given value.

If a generator has 120 volts and 22 amps, how many ohms are needed so the generator will not explode.

daser333 [38]

120 volt divided by 22 ampere
= 5.4545454545455 ohm (Ω)
P = V × I
= 120 volt × 22 ampere
= 2640 watt (W)
