Question

If the required pressure in the tyre of a car is $199\ kPa,$ then

What is the gauge pressure?
What is the absolute pressure?

✓

Answer

Gauge pressure,

$\therefore\text{P}_\text{g}=199\text{k Pa}$

Abosolute pressure,

$\text{P}=\text{P}_\text{a}+\text{P}_\text{g}[\because$ From equation $(i)]$
$=101\text{k P}+199\text{K Pa}$
$=300\text{k Pa}$
