Question

An air compressor and takes atmospheric Air at 14.7 PSI and increases its pressure to 150 psi ( Gauge). the pressurized air is stored in a horizontal tank. what is the absolute pressure of air inside the tank

Answer 1

The absolute pressure of air inside the tank is 164.7 psi.

Step-by-step explanation:

Given that,

Atmospheric pressure = 14.7 Psi

Gauge pressure = 150 psi

We need to calculate the absolute pressure of air inside the tank

Using formula of absolute pressure

`P_(ab)=P_(g)+P_(atm)`

Where,
`P_(g)` = gauge pressure

`P_(atm)` =atmospheric pressure

Put the value into the formula

`P_(ab)=150+14.7`

`P_(ab)=164.7\ psi`

Hence, The absolute pressure of air inside the tank is 164.7 psi.
