Answer:
The Gauge pressure at 9 meters depth is
Explanation:
Gauge pressure is the difference between absolute pressure and some reference pressure, most commonly atmospheric pressure. The increment in pressure caused by a static fluid is given by:
where is the density of the liquid, g is the accleration due to gravity and d is the depth.
Now, we see that is linearly proportional to d, and we can assume that remains constant, because liquids are usually not compressible.
Given that the greater depth is simply 3 times the smaller depth:
at of depth will also be three times the gauge pressure at of depth.
We could also have calculated ny using:
and used this result to calculate the gauge pressure. These are both similar methods that yield the same result
The downward force on the 2. 67-cm piston that is required to lift a mass of 2000 kg supported by the 20-cm piston is 350 N.
<h3>What is pascal law?</h3>
Pressure applied to a closed system of fluid will be transfer at each point of the fluid and the boundaries of the system.
Let suppose at the two point of such system the input force apllied is F₁ and output force we get is F₂. The area of this points is A₁ and A₂ respectively. As the pressure at both point is same. Then by the pascal law,
In case of radius,
Two pistons of a hydraulic lift have radii of 2. 67 cm and 20. 0 cm, respectively. Thus,
The downward force on the 2. 67-cm piston that is required to lift a mass of 2000 kg supported by the 20-cm piston is The force applied on second piston is,
Put the values in the above formula,
Thus, the downward force on the 2. 67-cm piston that is required to lift a mass of 2000 kg supported by the 20-cm piston is 350 N.
