Steel Cylinder Equipped with a Pressure Gauge

A steel cylinder equipped with a pressure gauge contains compressed gas. The pressure gauge provides readings of the pressure inside the cylinder at different temperatures. We are given that at a temperature of 10°C, the pressure gauge reads 0.26 MPa, and at a temperature of 32°C, the pressure gauge reads 0.28 MPa. We need to determine the thermal pressure coefficient based on this data.

To calculate the thermal pressure coefficient, we can use the formula:

Thermal Pressure Coefficient (β) = ΔP / P₀ΔT

Where: - ΔP is the change in pressure (P₂ - P₁) - P₀ is the initial pressure (P₁) - ΔT is the change in temperature (T₂ - T₁)

Let's calculate the thermal pressure coefficient using the given data.

Calculation:

Given: - Initial pressure (P₁) = 0.26 MPa - Final pressure (P₂) = 0.28 MPa - Initial temperature (T₁) = 10°C = 283.15 K - Final temperature (T₂) = 32°C = 305.15 K

Using the formula mentioned above, we can calculate the thermal pressure coefficient (β):

β = (P₂ - P₁) / (P₁ * (T₂ - T₁))

Substituting the given values:

β = (0.28 - 0.26) / (0.26 * (305.15 - 283.15))

Calculating the value:

β ≈ 0.02 / (0.26 * 22)

β ≈ 0.02 / 5.72

β ≈ 0.00349

Therefore, the thermal pressure coefficient based on the given data is approximately 0.00349.

Please note that the above calculation assumes that the volume of the cylinder remains constant. If there are any changes in the volume of the cylinder with temperature, the calculation may vary.
