A mercury manometer is connected between two points in a piping system that contains water. The downstream tap is $6 \mathrm{ft}$ higher than the upstream tap, and the manometer reading is $16 \mathrm{in}$.

FIGURE P4.5 Inclined manometer (not to scale).

If a pressure gage in the pipe at the upstream tap reads $40 \mathrm{psia}$, what would a pressure gage at the downstream tap read in (a) psia, (b) dyn $/ \mathrm{cm}^{2}$, (c) $\mathrm{Pa}$, (d) $\mathrm{kg}_{\mathrm{f}} / \mathrm{m}^{2}$ ?
