Question

What is 100 kPa in psia?

Answer 1

Answer:

The pressure in pounds per square inch (psi) equals 14.50 psi.

Explanation:

Since psi stands for 'pounds per square inch' and Pascals stands for 'Newtons per square meters'

We can write the given pressure as

$Pressure=100kPa\\\\Pressure=100\times 10^{3}N/m^{2}$

Now since 1 Newton of force equals 0.22481 Pound force also

since 1 meter equals 39.37 inches

Using the above values we get

$Pressure=100\times 10^{3}\times \frac{0.22481lb}{(39.37)^{2}inch^{2}}$

thus the pressure becomes

$Pressure=100\times 10^{3}\times \frac{0.22481}{(39.31)^{2}}pounds/inch^{2}\\\\Pressure=14.50psi$
