Question

how many pounds of pressure is required to raise water to a height of 30 feet.​

Answer 1

ressure can be illustrated by using the common weight and volume relationships of water:

One cubic foot of water weighs 62.4 pounds

One gallon weighs 8.3 pounds (from 62.4 lbs. divided by 7.48 gal per cu. ft.)

One cubic inch weighs 0.036 pounds (from 62.4 lbs. divided by 1,728 cu. in. per cu. ft.)

For example, using these relationships, stack twelve 1-inch cubes of water one on top of the other. These weigh 12 x 0.036 pounds or 0.433 pounds. The area under the column is one inch square (1 in. x 1 in.). The column exerts 0.433 pounds per square inch of pressure.

One pound per square inch (psi) of pressure can be created using a 1-in. square column of water nearly 28 inches or 2.31 feet high.

Answer 2

43.3 feet is the answer
