Answer is an increase in pressure will cause an decrease in the pressure
Answer:
Basically there are two principal differences between the convection and conduction heat transfer
Explanation:
The conduction heat transfer is referred to the transfer between two solids due a temperature difference, while for, the convective heat transfer is referred to the transfer between a fluid (liquid or gas) and a solid. Also, they used different coefficients for its calculation.
We can include on the explanation that conduction thermal transfer is due to temperature difference, while convection thermal transfer is due to density difference.
Answer:
Tout à fait les gens sont nuls
Answer:
57.8408 kPa
Explanation:
Data provided in the question:
Density of oxygen contained, ρ = 2.0 kg/m³
Temperature, T = 25 °C = 25 +273 = 298 K
Atmospheric pressure = 97 kPa.
Now,
Pressure due to gas = ρRT
Here,
R is the gas constant = 259.8 J/kg.K
Thus,
Absolute Pressure due to oxygen = 2 × 259.8 × 298
= 154840.8 Pa
= 154840.8 × 10⁻³ kPa
= 154.84 kPa
Thus,
Gage pressure = Absolute Pressure - Atmospheric pressure
= 154.84 kPa - 97 kPa
= 57.8408 kPa
