Question

A vertical dam has a semicircular gate as shown in the figure.
The total depth *d* of the figure is 42 m, the height
*h* of air above the water level is 6 m, and the width
*w* of the gate is 8 m. Find the hydrostatic force against
the gate. (Round your answer to the nearest whole number. Use 9.8
m/s^{2} for the acceleration due to gravity. Recall that
the weight density of water is 1000 kg/m^{3}.)

A vertical dam has a semicircular gate. The gate has diameter 4
meters, is the top half of a circle,
and the diameter is at a depth of 10 meters. Find the fluid force
against the gate

A triangular plate with base 6 m and height 2 m is submerged
vertically in water such that the highest vertex of the plate is 4
meters below the surface and the base is horizontal to the
surface.
4 m ( from water surface to top of triangle )
6 m ( triangle width )
2 m (triangle height )
Express the hydrostatic force against one side of the plate as
an integral and evaluate it. (Round your answer to...

A dam is inclined at an angle of 30° from the vertical and has
the shape of an isosceles trapezoid 200 ft wide at the top and 100
ft wide at the bottom and with a slant height of 140 ft. Find the
hydrostatic force on the dam when it is full of water. (Round your
answer to the nearest whole number. Recall that the weight density
of water is 62.5 lb/ft3.)

A dam is inclined at an angle of 30° from the vertical and has
the shape of an isosceles trapezoid 160 ft wide at the top and 80
ft wide at the bottom and with a slant height of 110 ft. Find the
hydrostatic force on the dam when it is full of water. (Round your
answer to the nearest whole number. Recall that the weight density
of water is 62.5 lb/ft3.)

Find the total force on a semi-circle (half-circle) shaped dam
where the top of the dam is the diameter of the circle, and the
diameter of the circle is 12 m. The water rises to the top of the
dam. Set up the integral needed to solve the problem, but do not
integrate. (Hint: The density of water is 1000 kg/m3 , and g = 9.8
m/s2 .)

Part A) The air pressure above the liquid in figure is 0.488 atm
. The depth of the air bubble in the liquid is h = 37.9 cm and the
liquid’s density is 847 kg/m3 . The acceleration of gravity is 9.8
m/s 2 .
Part B) A ship sailing from the ocean into a fresh water harbor
sinks slightly deeper into the water. How does the buoyant force on
it change?
1. It doesn’t change at all.
2. It...

1A) Use integration to find the amount
of fluid force exerted against one side of the submerged triangular
plate
An equilateral triangular plate with sides 8 m is submerged
vertically in water so that the base is even with the surface.
Express the hydrostatic force against one side of the plate as an
integral and evaluate it. (Round your answer to the nearest whole
number. Use 9.8 m/s2 for the acceleration due to
gravity. Recall that the weight density of...

A bubble having a diameter of 82 cm is re- leased from a depth
of 5.1 m from the bottom of a swimming pool. The temperature of the
water at the surface is 20◦C, whereas it is 15◦C at the bottom.
What will the diameter of the bubble be when it reaches the
surface? The acceleration of gravity is 9.8 m/s2 and the density of
water is 1000 kg/m3. Answer in units of cm.

QI: An open tank as shown in figure (1) has a vertical
partition and on one side contains gasoline with a density p= 700
kg m' at a depth of 4 m. A rectangular gate that is 4m high and 2m
wide and hinged at one end is located in the partition. Water is
slowly added to the empty side of the tank. At what depth, h, will
the gate start to open?

A trapezoidal plate, with 9m and 5m bases and 3m height, is
submerged vertically in a tank of water so that its top is 2m to
the water surface (as figure below). Calculate the hydrostatic
force against one side of the plate. (Water mass density ρ = 1000
kg/m3, and g = 9.8 m/s2).
