The pressure at the top of the water in a city's gravity-fed
reservoir is 1.0×105N/m2.
Part A
Determine the pressure at the faucet of a home 39 m below the
reservoir.
Express your answer to two significant figures and include the
appropriate units.
Answer
P = Po + rho * g * h
Po = 1 x 10^5 N/m^2
rho = 1000 kg /m^3
g = 9.8 m/s^2
h = 39 m
rho * g * h = 382200
P = 1 x 10^5 + 382200
P = 482200 N/m^2
P = 4.8 x 10^5 N/m^2
