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 0.700 L/s, with an output pressure of 2.00 x 105 N/m². You may 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 (in N/m²) at this point? N/m² (b) The hose goes over the foundation wall, losing 1.70 m in height, and widens to 4.00 cm diameter. What is the pressure now (in N/m²)? N/m²

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 0.700 L/s, with an output pressure of 2.00 x 105 N/m². You may 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 (in N/m²)
at this point?
N/m²
(b) The hose goes over the foundation wall, losing 1.70 m in height, and widens to 4.00 cm diameter. What is the pressure
now (in N/m²)?
N/m²
