problem 7: 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 0.65 l/s, with an output pressure of 1.75 × 105 pa. (a) The water enters a hose with a 3.00-cm inside diameter and rises 2.50 m above the pump. What is its pressure at this point? (b) The hose goes over the foundation wall, losing 0.500 m in height, and widens to 4.00 cm in diameter. What is the pressure now? You may neglect frictional losses in both parts of the problem.
