Answer:
a) The difference in mercury levels in the manometer is 2 centimeters.
b) The gage of the gas is 2.670 kilopascals.
Explanation:
a) Pressure in gases is absolute. A manometer helps to determine the hydrostatic difference between pressure of the gas () and atmospheric pressure (), both measured in pascals. A kilopascal equals 1000 pascals and 1 meter equals 100 centimeters. That is:
(1)
Where:
- Density of mercury, measured in kilograms per cubic meter.
- Gravitational acceleration, measured in meters per square second.
- Difference in mercury levels, measured in meters.
If we know that , , and , the difference in mercury levels in the manometer is:
The difference in mercury levels in the manometer is 2 centimeters.
b) The gage pressure is the difference between gas pressure and atmospheric pressure: (, )
(2)
The gage of the gas is 2.670 kilopascals.

Answer:
Some general principles are given below in the explanation segment.
Explanation:
Sewage treatment seems to be a method to extract pollutants from untreated sewage, consisting primarily of domestic sewage including some solid wastes.
<u>The principles are given below:</u>
- Unless the components throughout the flow stream become greater than the ports or even the gaps throughout the filter layer, those holes would be filled as either a result of economic detection.
- The much more common element of filtration would be the use of gravity to extract a combination.
- Broadcast interception or interference.
- Inertial influence.
- Sieving seems to be an excellent method to distinguish particulates.
