That depends on what information is provided. If you don't have any information, you may actually need to measure the speed of the water; or you may want to measure the flow (for example, in liters per second), and the pipe diameter, and then calculate the speed from that.
You will need more information in order to calculate.
Q = V*A
Q is flow rate
V is fluid velocity
A is x-sectional Area
You find the speed.
Assuming the speed of light in air is already known (it is close to the speed of light in a vacuum), you might check how the light refracts when it changes from air to water (at what angle), and then use Snell's Law.
In salt water that is free of air bubbles or suspended sediment, sound travels at about 1560 m/s. The speed of sound in seawater depends on pressure (hence depth), temperature (a change of 1 °C ~ 4 m/s),and empirical equations have been derived to accurately calculate sound speed from these variables. In pure water the speed of sound is less than in ocean water.
Can you calculate the ID of a pipe when you have the OD to be 10.75" and the wall thickness to be 0.5"Depends on what you know about it. If you have the outer diameter and you know the wall thickness, then ID = OD-2 x wall thickness
Due to friction between the fluid and the walls of the pipe, pressure increases within the pipe.
no
Go to: http://www.techcalcs.com/calculators/pipeprop.php and use the calculator Otherwise calculate the volume displaced by the pipe and multiply by the density of the displaced water. This gives the bouyancy of the pipe
Depends on the diameter of the pipe and the speed at which the water travels through it.
Speed of light in water = speed of light in vacuum/refractive index of water
Yes, it is actually one of the questions on a master plumbers exam
You find the speed.
measure the radius of the pipe. (half the diameter - the width of the pipe) then measure the length of the pipe. then use the formula pi (3.14) x radius2 x length. the answer is the volume in the pipe
Find the volume in cubic feet and multiply by 7.48
You need to know the radius (1/2 the inside diameter) and the length of the pipe. Then, you use this formula to calculate the volume:Pi (3.1416) x r2 x length
Assuming that the pressure remains at a constant, reducing the diameter of the pipe will increase the water flow. On the contrary, increasing the diameter would cause the water to flow at a much slower rate.
Insufficient information, one needs to know the pressure of the water entering the pipe, the relative heights of both ends the pipe, the pressure of the water at the discharge of the pipe, the geometry of the pipe including the number and types of turns, and the pipe material or internal friction coefficient. Then you can calculate the flow.
Assuming you mean water in a pipe, the speed of the moving water can be changed by changing the pressure, the force pushing the water. It can also be changed by changing the characteristics of the pipe (larger, smoother inner walls, etc.)
