Question

The unit pound per square inch (psi) is equal to `6.8 * 10^-2` atm. What is the equivalent pressure in pascals?

Answer 1

To answer this question, you need to know the conversion from atmospheres (atm) to pascals

Explanation:

1atm = 101.1 kPa
1 kPa = 1000 Pa

start with what is given;

`6.8*10^-2` atm `(101.3kPa)/(1atm)` `(1000Pa)/(1kPa)`= `6.9*10^3` `Pa`
