Assuming the density of seawater is 1.03 g/cm3, find the total weight of water on top of a nuclear submarine at a depth of 185 m if its (horizontal cross-sectional) hull area is 3200 m2. In atmospheres, what pressure would a diver experience at this depth? Do you think that occupants of a damaged submarine at this depth cou
A large cylinder tub of water rests at the edge of a table 150.0 cm high. The tub is full, it is 110.0 cm tall with top area of 1000 cm^2. If a hole 1.0 cm^2 is made in its side 10.0 cm above the bottom: (a) Determine the speed of the water as it leaves the side. (b) How far will it reach when it hits the ground?
A log of wood is floating in water with 40% of its volume above the surface of the water. if the volume of the log is 0.4 m^3, find the mass of the log. a. 200kg b. 240 kg c. 160 kg d. 16 kg
Water is pumped through a pipe to a tank at the top of a building. The pressure of the water at ground level is 2.2* 10^5 Pa and at the tank, the pressure is atmospheric. If the diameter of the pipe is the same throughout, find the height at which the tank is located. Atmospheric pressure may be assumed as 1.0 * 10^5 Pa and G as
How do architects and designers effectively incorporate geometic planes and lines to create living designs? REsources are also included.
A U tube open at both ends is partially filled with water. Oil having a density of 750 kg/cubic meter is then poured into the right arm and forms a column L = 5.00 cm high. (a) Determine the difference h in the heights of the two liquid surfaces. The right arm is then shielded from any air motion while air is blown across the
Please do not include your response in a .pdf or .cdx format, but Word documents are okay. Thanks! Here's the actual problem: A U-shaped tube, open to the air on both ends, contains mercury. Water is poured into the left arm until the water column is 13.1 cm deep. How far upward from its initial position does the mercury i
During each heartbeat, approximately 70cm³ is pushed from the heart at an average pressure of 105mm-Hg. Calculate the power output of the heart, in watts, assuming 70 beats per minute. *please explain this as simply as possible- thanks so much :)
What gauge pressure in the water mains is necessary if a firehose is to spray water to a height of 15m?
A 5/8 inch (inside) diameter garden hose is used to fill a round swimming pool 6.1m in diameter. How long will it take to fill the pool to a depth of 1.2m if water issues from the hose at a speed of 0.33m/s? *note- please explain this in the simplest way possible if you can! thank you :)
A 3.15kg piece of wood (SG= .50) floats on water. What minimum mass of lead, hung from it by a string, will cause it to sink? *note- please explain this in the simplest way possible if you can! thank you :)
The acceleration of a marble in a certain fluid is proportional to the speed of the marble squared and is given in SI units) by a=-3.00 v^2 for v greater than 0. If the marble enters this fluid with a speed of 1.20 m/s, how long will it take before the marble's speed is reduced to half of its initial value?
The diagram shows a gear pump. The maximum diameter of the gear wheels is 80 mm, the diameter of the roots of the teeth is 50 mm and the tooth width is 20mm. If the pump is driven at 500 rpm, please estimate the volume of oil pumped every minute. If the pressure difference across the pump is 50 bar, what shaft power has to be
Determine the specific gravity of spherical particles, D=(1/200 in), which drop through air at 33degrees F at a speed U of 0.3 ft/s. The drag force on a small sphere in laminar motion is given by 3(pi)(mu)DU. This problem is in Fluid Mechanics by Victor Streeter.
If one cubic centimeter of water has a mass of 1 gm, find the pressure at a depth of 5m in a tank of water.
This is a past exam question. Please help me understand how to go about questions a and b. I think I need some kind of double integral or something? Systems Engineering B The shape of the hull of a small barge of width w, length l and depth d, can be approximated by the multivariable function f(x,y), where:
