How fast does the water move through the nozzle?
919335
If a molecule of the water is moving at 2m/s through the hose, it is because of the nozzle, not despite it. That molecule travels through the nozzle at 2m/s.

1,000000,0000000 that is how fast sound really is.\n\nbut to answer you question just listen and watch a jet after the jet passes then it takes 15 seconds before you here the sound because the jet has broken through the sound barrier.

around 1/6th that of earth so around 1.64m/s

Given a fixed power of heat input water would take longer due to its specific heat capacity being large.  4180Joules/kg/degree, compared with 450 for iron & 880 for Aluminium (figures STRICTLY only from memory and not to be relied on)\nOther than that are consideration of good conduction of heat in metals versus convection transporting the heat quickly within the water.\nAlso practically speaking, you might need to allow for evaporative heat loss from the water surface.

The water starts from one end and reaches the other end in 30 minutes\n\nThe distance traveled is 1700 meter. Time taken 30 minutes = 1800 second.\n\nThe velocity is distance traveled per second. Therefore, it is 1700 /1800 m/s =0.94m/s

its all to do with weight displacement and the volume of water

From what I recall, the flow rate (GPM) would be the same throughout the pipe.  The equation of continuity for incompressible fluid flow is\n\nA(1)*V(1)=A(2)*V(2)\n\nwhere A is the cross sectional area and V is the velocity of the water (1 and 2 are the before and after positions).  Looking at this, the only thing the different diameter pipes (and thus the CSA) affects is the velocity of the fluid.  When you have a reduction in CSA, the velocity increases (if you partially cover a garden hose, the water shoots out faster), but you're still getting the same amount of fluid out per time unit.\n\nTry this - time how long it takes to fill a cup using your kitchen faucet.  Then, fill the same cup, but cover your faucet like you would a garden hose so that the water shoots out faster, and time that fill.  The times should be the same, plus or minus timing errors.

Dear Little Giggl:  I think the answer to your question is VELOCITY, but it is NOT viscosity - which is the RESISTANCE property in liquid, that prevents quick flowing.\n\nFlow dynamics is said to be measured according to density and pressure which help determine velocity measurement of liquid.\n\nThank you for the question. . .it helped me to learn something.

"Rapid" sperm travel 25 microns/second, or one sperm length every 2 seconds.  "Slow" progressive sperm swim 5 - 24 microns / sec. \n\nRapid sperm are pretty quick.  Slow sperm, not so much.  \nPS - They figure it out by watching them swim under a microscope that has a little micron ruler.

About 1000 feet per sec.

Atomized fluids tend to have problems with air resistance which can slow the particles down rather quickly. Getting enough velocity to go with the very small mass is a real problem. \n\nOf course I'm now sure how you define atomized. A fire nozzle in the spray setting can go about 25 feet plus on a still day but that stream really isn't what I would call atomized.

The volumetric flow rate is proportional to the pressure at the bottom (which is rho*gh, or density times gravity times fluid height) and to the area of the orifice (which is pi*r^2, where r is the radius, 1 mm = 0.001 m).  There is a valve constant involved, which you can assume is equal to 1 if you're not given additional information.

The static pressure (P) of the water in the tank is\n\nP = p*g*h\n\nwhere p is the density of water, g is the gravitational acceleration, and h is the height of water. When the water exits the hole at the bottom of the tank it has kinetic energy per unit volume given by\n\nK = 0.5*p*v^2\n\nwhere v is the exit speed.\n\nThe jet travels a horizontal distance L hitting the ground. \n\nL = v*t\n\nwhere t is the travel time, which can be solved for by knowing how high the tank is above the ground. The water falls through a distance Y under the influence of gravity since there is no y-component to the initial velocity.\n\nY = 0.5*g*t^2.\n\nSolving for t yields\n\nt = sqrt(2*Y/g)\n\nwhich gives a speed of \n\nv = L/t = L*sqrt(0.5*g/Y).\n\nEquating the fluid potential energy per unit volume (pressure) to the kinetic energy we have\n\np*g*h = 0.5*p*v^2\n\ncanceling out p and substituting v gives\n\ng*h = 0.5*L^2*0.5*g/Y\n\nSolving for h, the height of the fluid, yields\n\nh = L^2/(4*Y)\n\nY = 1 m according to the picture provided. Of course, this is a dynamic problem as fluid exits the hole the height of the fluid will change as will the exit speed and impact distance. The height here is for the initial jet of water.\n\nThe links below provide more information regarding pressure, Torricelli, and Torricelli's law.

This is not as simple of a question as you have assumed.  The rate of cooling will depend on the mass of the water, that is, how much water you have.  Secondly it will depend on how well the container conducts heat.  Thirdly, what is the surface area of the container.  The greater the surface area, the faster the water will cool.  You must also consider air movement in the immediate area of the container.  If there is air movement, the cooling rate will be affected by how much air flows over the surface of the container.  Next, you must know the temperature at which the water boils.  The higher the altitude the lower the boiling point.  Finally what is the temperature and humidity in the room?

Sound travels fastest through solids. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it. In fact, sound waves travel over 17 times faster through steel than through air. The exact speed of sound in steel is 5,960 meters per second (13,332 mph)! But, this is only for the majority of solids. The speed of sound in all solids are not faster than in all liquids.
