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.

Answer #1

. 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 1.25 L/s, with an output pressure of 3.00×105 N/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...

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...

A sump pump is draining a flooded basement at the rate of 0.850
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 2.90 m above the pump.
What is its pressure at this point?
(b) The hose then loses 2.00 m in height from this point as it
goes over the foundation wall, and widens to...

An industrial pump is to be used to supply water from Lake Bonno
to an agricultural field located 500 m away from the lake, and at
an elevation of 20 m above the surface of the lake. If the
horse-power of the pump is 45-hp, what is the discharge that can be
delivered by using a pipe of diameter D = 0.4 m and a friction
coefficient of f = 0.015? Neglect all minor losses. Is the flow
laminar or...
