1.08 atm is the pressure for a certain tire in atmosphere.
Explanation:
One kilo pascal (1 kPa) corresponds to 1000 pascal. Another common unit used for pressure is atmosphere (symbolised as ‘atm’). 1 atm refers the standard atmospheric pressures and corresponds to 760 mm Hg and 101.3 kPa. Atmospheric pressures are commonly referred as square inches (psi)/ pounds.
[tex]1 \mathrm{atm}=101.3 \mathrm{kPa}=101,325 \mathrm{Pa}=760 \mathrm{mm} \mathrm{Hg}=760 \text { torr }=14.7 \mathrm{lb} / \mathrm{in}^{2}(\mathrm{psi})[/tex]
Given:
The air pressure for a certain tire = 109 kPa
We need to find pressure in atmospheres
So, we know,
1 atm = 101.3 kPa
Hence,
[tex]\frac{109 \mathrm{kPa}}{1} \times \frac{1 \mathrm{atm}}{101.3 \mathrm{kPa}}=1.076=1.08 \mathrm{atm}[/tex]
1.08 atm is the pressure for a certain tire in atmosphere.
The pressure in atmosphere is = 1.08 atmosphere.
The atmospheric pressure can be measured using a barometer in units of measurement called atmospheres or bars.
To convert 109 kPa pressure to atmosphere,
101.325 kPa = 1 atm
109 kPa = X
Cross multiply to solve for x,
[tex]x = \frac{1 \times 109}{101.325} [/tex]
X = 1.075
X = 1.08 atmosphere.
