Question

You measure the pressure at 10 feet in a column of water and determine it to be 43.36 lbs/in. What would this measurement be in N/m2? 18.2 N/m2 299,034 N/m2 ) 187,334 N/m2 19.9 N/m 2

Answer 1

299034 N/m²

Step-by-step explanation:

1 lbs = 4.448 N

1 in = 0.0254 m

1 in² = 0.254² m²

thus,

`1(lbs)/(in^2) = (4.448N)/(0.0254^2m^2)=6894.413N/m^2`

therefore,

43.36lbs/in² in N/m² will be

= 43.36 × 6894.413

= 298941.77 N/m² ≈ 299034 N/m²

so the correct option is 299034 N/m²
