1–16 The pascal (Pa) is actually a very small unit of pressure. To show this, convert 1 Pa=1 N/m21 Pa=1 N/m2 to lb/ft2lb/ft2. Atmosphere pressure at sea level is 14.7 lb/in214.7 lb/in2. How many pascals is this?

Respuesta :

Answer:

[tex]14.7\ \frac{lb}{in^2}[/tex] is 101325.9 Pa.

Explanation:

Given that

[tex]Atmospheric\ pressure\ at\ sea\ level\ is\ 14.7\ \frac{lb}{in^2}[/tex]

We know that

[tex]1\ pascal\ =1\dfrac{N}{m^2}[/tex]

Pascal is the unit of pressure

We know that

[tex]1\ \frac{lb}{in^2}=6894.76\ Pa[/tex]

So

[tex]14.7\ \frac{lb}{in^2}=6894.76\times 14.7\ Pa[/tex]

[tex]14.7\ \frac{lb}{in^2}=101325.9\ Pa[/tex]

So we can say that one

[tex]14.7\ \frac{lb}{in^2}[/tex] is 101325.9 Pa.
