Question

Calculate pressure when height is equals to 152 metre density is equals to 6.8 gram per centimetre cube in newton per metre square

Answer 1

Given:

Height, h = 152 m

Density, d = 6.8 gm/cm³

To Find:

The pressure in newton per metre square.

Calculation:

- Convert the density into kg / m³:

d = 6.8 gm/cm³

⇒ d =  6.8 × 10⁻³/10⁻⁶ kg/m³

⇒ d =  6.8 × 10³ kg/m³

- The pressure is given as:

P = h d g

⇒ P = 152 × 6.8 × 10³ × 9.8

⇒ P = 10129280 N/m²

⇒ P ≈ 1.013 × 10⁷ N/m² (approx)

- So, the pressure in newton per metre square is approximately 1.013 × 10⁷ N/m².
