2. The cross-sectional area of an underground pipe is $40{\mathrm{cm}}^2$. It tapers as it rises, carrying water to a faucet located a vertical height $h=12.5\mathrm{m}$ above the pipe. The faucet opening has an area of $3{\mathrm{cm}}^2$. If water emerges from the faucet at $12\mathrm{m}/\mathrm{s}$, what is the pressure in the underground pipe? a) $237\mathrm{kPa}$ b) $256\mathrm{kPa}$ c) $276\mathrm{kPa}$ d) $284\mathrm{kPa}$ e) $295\mathrm{kPa}$
