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 0.65 L/s, with an output pressure of 3.15 × 105 Pa. The water enters a hose with a 2.9 cm inside diameter and rises 2.1 m above the pump. What is its pressure at this point, in pascals? You may neglect frictional losses. The hose then goes over the foundation wall, losing 0.65 m in height, and widens to 4.4 cm in diameter. What is the pressure now, in pascals? You may neglect frictional losses.

60. 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 0.750 L/s, with an output pressure of
3.00×105N/m2.
(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....

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 0.600 L/s, with an output pressure of 3.50 ✕ 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...
