Question

If the pressure inside a rubber balloon is \(1500 \mathrm{mmHg},\) what is this pressure in pounds-force per square inch (psi)?

Short answer

Answer: The pressure inside the rubber balloon is 29.00 psi.

Step-by-step solution

Write down the given pressure

The pressure given inside the rubber balloon is 1500 mmHg.

Use the conversion factor

To convert the pressure from mmHg to psi, we'll use the conversion factor: 1 mmHg = 0.0193368 psi.

Multiply the pressure by the conversion factor

Now, we'll multiply the given pressure (1500 mmHg) by the conversion factor to get the pressure in psi: Pressure (psi) = Pressure (mmHg) * Conversion factor \(Pressure\ (psi) = 1500\ \text{mmHg} * 0.0193368\ \frac{\text{psi}}{\text{mmHg}}\)

Calculate the result

Multiply the pressure by the conversion factor to get the result: \(Pressure\ (psi) = 28.9952\ \text{psi}\)

Round the result

In most cases, people prefer to round results to a couple of decimal places. So, we'll round the result calculated in the previous step to 2 decimal places: Pressure (psi) = 29.00 psi And there is the answer: The pressure inside the rubber balloon, expressed in pounds-force per square inch (psi), is 29.00 psi.
