A sump pump is draining a flooded basement at the rate of 0.700 L/s, with an output pressure of 3.50 ✕ 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 3.40 m above the pump. What is its pressure at this point?

_______ N/m2

(b) The hose then loses 1.50 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?

_______N/m2
