Answer:
1) The pressure difference is 4.207 kilopascals.
2) 2.5 pounds per square inch equals 5.093 inches of mercury and 5.768 feet of water.
Explanation:
1) We can calculate the gas pressure difference from the U-tube manometer by using the following hydrostatic formula:
(Eq. 1)
Where:
- Relative density, dimensionless.
- Density of water, measured in kilograms per cubic meter.
- Gravitational acceleration, measured in meters per square second.
- Height difference in the U-tube manometer, measured in meters.
- Gas pressure difference, measured in kilopascals.
If we know that ,
,
and
, then the pressure difference is:
The pressure difference is 4.207 kilopascals.
2) From Physics we remember that a pound per square unit equals 2.036 inches of mercury and 2.307 feet of water and we must multiply the given pressure by corresponding conversion unit: ()
2.5 pounds per square inch equals 5.093 inches of mercury and 5.768 feet of water.
Answer:
Explanation:
Thermal reservoir:
It is the body which have infinite amount of heat capacity and store large amount of heat.The temperature of thermal reservoir is constant and does not change with time.The temperature of thermal reservoir is not change even heat is going out from reservoir or heat going inside the reservoir.The temperature of thermal reservoir remains constant and does not depend on the surroundings.
