Answer :
Final answer:
The static pressure on the plumbing faucet 40 ft. above the main is approximately 77.32 psi.
None of the option is correct.
Explanation:
To find the static pressure on a plumbing faucet 40 ft. above the water main with a pressure of 60 psi:
1. Convert the height to pressure using the equation: 1 psi per 2.31 ft of height.
2. Calculate the pressure due to the height difference: 40 ft / 2.31 ft = 17.32 psi
3. Add the pressure due to height to the pressure at the main: 17.32 psi + 60 psi = 77.32 psi
Therefore, the static pressure on the plumbing faucet 40 ft. above the main is approximately 77.32 psi.
None of the option is correct.
