Answer

\text{200,000 N}

3 steps

Identify the given values.
The pressure of oxygen for safe use ( $P$ ) is $1000 \text{ kPa}$ .
The area of the regulator opening ( $A$ ) is $0.2 \text{ m}^2$ .
Convert the pressure to Pascals (Pa) for consistency with SI units.
$1 \text{ kPa} = 1000 \text{ Pa}$ $P = 1000 \text{ kPa} = 1000 \times 1000 \text{ Pa} = 1,000,000 \text{ Pa}$
Calculate the force ( $F$ ) using the formula $F = P \times A$ .
We assume the question implicitly asks for the force exerted by the oxygen at the regulator opening at the safe use pressure.
$F = P \times A$ $F = (1,000,000 \text{ Pa}) \times (0.2 \text{ m}^2)$ $F = 200,000 \text{ N}$
The force exerted by the oxygen at the regulator opening is $\text{200,000 N}$ .
