What is the approximate water flow rate if the pitot reading was 15 psi and the outlet coefficient is 0.8?

• A. 1155 gpm
• B. 1200 gpm
• C. 1000 gpm
• D. 1100 gpm

Answer: (A)

To determine the approximate water flow rate based on a pitot reading and an outlet coefficient, we can use the formula that relates these parameters. The formula for flow rate (Q) in gallons per minute is derived from the pitot pressure in psi and adjusted for the outlet coefficient. Specifically, the flow rate in gpm can be calculated using the following equation: \[ Q = C \times \sqrt{P} \times 29.83 \] Where: - Q is the flow rate in gpm. - C is the outlet coefficient. - P is the pitot pressure in psi. In this scenario, the pitot reading is 15 psi and the outlet coefficient is 0.8. Plugging these values into the formula gives us: \[ Q = 0.8 \times \sqrt{15} \times 29.83 \] First, we calculate the square root of 15, which is approximately 3.87. Then, substituting back into the equation: \[ Q = 0.8 \times 3.87 \times 29.83 \] This results in: \[ Q \approx 0.8 \times 3.87 \times 29.83 \approx

To determine the approximate water flow rate based on a pitot reading and an outlet coefficient, we can use the formula that relates these parameters. The formula for flow rate (Q) in gallons per minute is derived from the pitot pressure in psi and adjusted for the outlet coefficient. Specifically, the flow rate in gpm can be calculated using the following equation:

[ Q = C \times \sqrt{P} \times 29.83 ]

Where:

• Q is the flow rate in gpm.

• C is the outlet coefficient.

• P is the pitot pressure in psi.

In this scenario, the pitot reading is 15 psi and the outlet coefficient is 0.8. Plugging these values into the formula gives us:

[ Q = 0.8 \times \sqrt{15} \times 29.83 ]

First, we calculate the square root of 15, which is approximately 3.87. Then, substituting back into the equation:

[ Q = 0.8 \times 3.87 \times 29.83 ]

This results in:

[ Q \approx 0.8 \times 3.87 \times 29.83 \approx
