A pump at the bottom of a 0.60 meter deep fishpond sprays water
from the surface at 2.4 liters/minute. If the intake pipe at the
bottom of the pond and output pipe at the waters surface each have
a 1.2cm diameter
a) what is the total pressure at the bottom of the pond where
the intake is located?
b) what is the magnitude of air pressure acting on the spray
at its highest point
c) what is the velocity of the water in the spray at the
highest point?
A horizontal meter stick is centered at the bottom of a
4.5-m-deep, 3.9-m-wide pool of water.
How long does the meter stick appear to be as you look at it
from the edge of the pool?
A pump takes water at 60°F from a large reservoir and delivers
it to the bottom of an open elevated tank 25 ft above the reservoir
surface through a 3 inch ID pipe. The inlet to the pump is located
10 ft below the water surface, and the water level in the tank is
constant at 160 ft above the reservoir surface. The pump delivers
150 gpm. If the total loss of energy due to friction in the piping
system...
A small water pump is used for an irrigation project. The pump
takes water in from a river at 10oC, 100 kPa at a mass
flow rate of 16.83 kg/s. The exit line enters a pipe that goes up
to an elevation 26.15 mm above the pump and river, where the water
runs into an open channel. Assume the process is adiabatic and that
the water stays at 10 oC. Find the required pump
work.
A pump must suck a well as deep as 20 m, water temperature 25 °
C, how the arrangement puts the pump depth so that water can be
pumped perfectly, count and use the required table
A centrifugal pump is to be used to pump water from a lake to a
storage tank which is 165 feet above the surface of the lake. The
pumping rate is to be 10 - 35 gal/min at a water temperature of
43°F. The water is used for drinking but will have to undergo
filtration and chlorine treatment because there is sediment in the
lake. The pump on hand can develop a discharge pressure of 60.0

A pump is to lift water from a source 10 ft below pump
centerline and to be discharged to a tank 60ft above pump
centerline. The installation uses 3”∅ and 2.5 “∅ pipe for suction
and discharge, respectively. A pump is to handle 200 gpm of water
at 80°F. The loss of head due to friction can be estimated equal to
8.5 ft. Determine: A) TDH B) WHP C)BHP if np = 60% D)time required
to fill the cylindrical tank...
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 0.55 L/s, with an output pressure of 2.95 × 105 N/m2.
A. The water enters a hose with a 2.8 cm inside diameter and
rises 2.2 m above the pump. What is its pressure at this point
N/m2? You may neglect frictional losses.
B. The hose goes over the foundation wall, losing 0.65 m...
A pump lifts 1000 (liters) of water from ground to a
tank on the roof of a building 100 (m) high. What is the potential
energy in the water? [ 1 (liter) = 1000 cm3 ]. Show all your steps
to the solution.
A skier is coming downhill. At one point she is 50 (m)
above the bottom of the hill and moving at 20 (m/s). What is her
speed as she reaches the bottom of the hill?
22.3 (m/s)...
An air bubble at the bottom of a lake 32.0m deep has a volume of
1.00 cm3.
If the temperature at the bottom is 2.2 ?C and at the top 20.2
?C, what is the radius of the bubble just before it reaches the
surface?
