Question: A sump pump (used to drain water from the basement of houses built below the water table) is draining a flooded basement at the rate of 0.55 L/s, with an output pressure of 2.9 Ã- 105 N/m2.
a) The water enters a hose with a 3.2 cm inside diameter and rises 2.4 m above the pump. What is its pressure at this point N/m2? You may neglect frictional losses.
b) The hose goes over the foundation wall, losing 0.55 m in height, and widens to 4.9 cm in diameter. What is the pressure now in N/m2? You may neglect frictional losses.
