You are building a house in the town of Springfield and a water tower is being built to service the town. The tower is 2km from your house and 5m higher than your house. The water in the water tower is at 1 atm and supplied at a rate of 2500 US gallons per day through a 4" internal diameter PVC pipe to your house. You estimate the frictional losses at 30J/kg. Before water enters your house, it passes through a booster pump to ensure sufficient water pressure for household use. The pump has rating of 0.1hp with 60% efficiency. a) Estimate the water pressure (atm) at the inlet to your house. b) To increase the house water pressure, should the pipes be larger or smaller
