A housing development is served by a water tower with the water level maintained between $60$ and $90$ feet above the ground,

depending on demand and water availability.

Responding to a resident's complaint about the low flow rate of water at his kitchen sink, a representative of the developer measured

the water pressure at the tap above the kitchen sink and at the junction between the water main $($a pipe connected to the bottom of

the water tower$)$ and the feed pipe to the house. The junction is $14\mathrm{.}3$ feet below the level of the kitchen tap. All water valves in the

house were turned off.

If the water level in the tower was $70\mathrm{.}0$ feet above tap level, what should be the gauge pressures $($ kPa $)$ at the tap and junction?

Tap:

$i$

$1$kPa

Junction:

kPa
