Question: A sump pump is draining a flooded basement at the rate of 0.500 L/s, with an output pressure of 3.00 ✕ 105 N/m2. Neglect frictional losses in both parts of this problem. (a) The water enters a hose with a 3.00 cm inside diameter and rises 3.00 m above the pump. What is its pressure at this point? N/m2 (b) The hose then loses 1.20 m in height from this point as it goes over the foundation wall, and widens to 4.00 cm diameter. What is the pressure now?
