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 top above the kitchen sink and at the junction between the water main la pipe connected to the bottom of: the water tower) and the feed pipe to the house. The junction is 15.0 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 79.0 feet above tap level, what should be the gauge pressures ( kPa) at the tap and junction? Junction: kPa kPa
