Question 6.1

What is the gauge pressure at the bottom of the cylinder?

To determine the gauge pressure at the bottom of the cylinder, we need to consider the weight of the fluid column above it.

The gauge pressure at a certain point in a fluid is equal to the pressure exerted by the fluid above that point. This pressure is caused by the weight of the fluid column.

In this case, the bottom of the cylinder is 4 meters below the surface of the fluid. The pressure at any depth in a fluid is given by the formula:

P = P0 + ρgh

Where:
- P is the pressure at a certain depth
- P0 is the atmospheric pressure
- ρ is the density of the fluid
- g is the acceleration due to gravity
- h is the depth

Since we are looking for the gauge pressure, we can ignore the atmospheric pressure term (P0). Assuming the fluid is water, the density (ρ) is approximately 1000 kg/m^3, and the acceleration due to gravity (g) is approximately 9.8 m/s^2.

Therefore, the gauge pressure at the bottom of the cylinder is:

P = ρgh
= (1000 kg/m^3)(9.8 m/s^2)(4 m)
= 39,200 Pa

So, the gauge pressure at the bottom of the cylinder is 39,200 Pa.

To find the gauge pressure at the bottom of the cylinder, we need to know the height of the liquid column inside the cylinder and the density of the liquid.

The gauge pressure at a certain depth in a fluid can be calculated using the following formula:

P = ρgh

Where:
P is the gauge pressure,
ρ is the density of the liquid,
g is the acceleration due to gravity, and
h is the height of the liquid column.

To determine the gauge pressure at the bottom of the cylinder, you need to know the density of the liquid in the cylinder and the height of the liquid column above the bottom.

Please provide the values for the density of the liquid and the height of the liquid column, and I can help you calculate the gauge pressure at the bottom of the cylinder.

To find the gauge pressure at the bottom of the cylinder, we can use the equation:

gauge pressure = total pressure - atmospheric pressure.

Since the gauge pressure is the pressure measured with respect to atmospheric pressure, we need to subtract the atmospheric pressure.

If the atmospheric pressure is not provided, we can use the standard atmospheric pressure at sea level, which is approximately 101,325 Pascals (Pa) or 1 atmosphere (atm).

So, the equation becomes:

gauge pressure = total pressure - 1 atm.

Let's assume the total pressure at the bottom of the cylinder is P_total. Then the gauge pressure will be:

gauge pressure = P_total - 1 atm.

Please provide the value for the total pressure at the bottom of the cylinder (P_total) to calculate the gauge pressure.
