What is the actual maximum height to which water will be lifted when the intake gauge reads 9 inches of mercury?

The maximum height to which water can be lifted is determined by the measurement of pressure in inches of mercury and the specific gravity of water. One inch of mercury (Hg) corresponds to a specific height of water that can be calculated using the following relationship:

1 inch of Hg is approximately equivalent to 0.0136 feet of water. This conversion factor is essential in determining how high water can be elevated based on the pressure indicated.

When the intake gauge reads 9 inches of mercury, the calculation for the height of water lifted is as follows:

1. Convert the inches of mercury to feet of water:

• 9 inches of Hg × 0.0136 feet of water/inch of Hg = 0.1224 feet of water per inch of mercury.

• Therefore, for 9 inches of mercury: 9 inches × 0.0136 feet/inch = 0.1224 feet × 9 = approximately 1.22 feet.

2. To find out the actual maximum height of water:

• The standard conversion shows that 1 inch of mercury will lift water approximately 1.133 feet, thus:

• 9 inches × 1.133 feet/inch = 10.
