Question

Jillian is trying to determine what helium tank pressure she needs to fill balloons for the student council dance. Find the unknown numbers in the table until you find the best answer to the question.
Which cylinder pressure will Jillian need if she plans to fill 90 balloons?

Answer 1

According to the typical Helium Cylinder/Balloon Chart, she will need 300 pounds of pressure to fill 90 balloons. Option D is correct.

What is pressure?

The force applied perpendicular to the surface of an item per unit area across which that force is spread is known as pressure. The force involved vertically to the surface of an object per unit area is pressure.

It is denoted by P. The pressure relative to the ambient pressure is known as the gauge pressure.

The complete question is:

Jillian is trying to determine what helium tank pressure she needs to fill balloons for the student council dance. Find the unknown numbers in the table until you find the best answer to the question. Which cylinder pressure will Jillian need if she plans to fill 90 balloons? Tank Pressure and Balloon Quantity Pressure in the helium cylinder (psi) Number of 9-inch balloons 100 30 150 ? 200? 250? 300?

According to the typical Helium Cylinder/Balloon Chart, she will need 300 pounds of pressure to fill 90 balloons (PSI.)

Simply divide the number of balloons by the total PSI to arrive at this figure.

⇒990/300

⇒3.333333 psi each.

The no of the 90-inch balloon is found as;

⇒3.33333 × 90

⇒300

According to the typical Helium Cylinder/Balloon Chart, she will need 300 pounds of pressure to fill 90 balloons.

Hence option D is correct.
