Updated: 3/11/2025

To calculate the velocity of water in a pipe, you can use the formula: velocity flow rate / cross-sectional area of the pipe. The flow rate can be measured in liters per second or cubic meters per second, and the cross-sectional area is the area of the pipe's opening. By dividing the flow rate by the cross-sectional area, you can determine the velocity of the water flowing through the pipe.

How can one calculate angular velocity from linear velocity?

To calculate angular velocity from linear velocity, you can use the formula: Angular velocity Linear velocity / Radius. This formula relates the speed of an object moving in a circular path (angular velocity) to its linear speed and the radius of the circle it is moving in.

How can one calculate the distance traveled by an object using its velocity and the time it has been in motion?

To calculate the distance traveled by an object, multiply its velocity by the time it has been in motion. This formula is distance velocity x time.

How can one calculate velocity from a position-time graph?

To calculate velocity from a position-time graph, you can find the slope of the line tangent to the curve at a specific point. This slope represents the instantaneous velocity at that point. Alternatively, you can calculate the average velocity over a specific time interval by finding the change in position divided by the change in time.

How can you calculate the resultant velocity of two velocities in the opposite dirction?

When two velocities are in opposite directions, subtract the smaller velocity from the larger one. The direction of the resulting velocity will be in the direction of the larger velocity. This is because the smaller velocity is effectively being subtracted from the larger one.

How can one find velocity using acceleration and time?

To find velocity using acceleration and time, you can use the formula: velocity acceleration x time. Simply multiply the acceleration by the time to calculate the velocity.

Can you calculate water velocity in pipe if just know head pipe diameter and pipe length?

Yes, it is actually one of the questions on a master plumbers exam

What is the maximum amount of water that can flow in a 2 inch pipe one half mile long?

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.

How can one Calculate the PSI of water in river based off velocity of the river?

To calculate the PSI of water in a river based on the velocity of the river, you can use the formula PSI = 0.433 * (velocity in feet per second)^2. This formula accounts for the pressure increase due to the velocity of the flowing water. Just plug in the velocity of the river in feet per second into the formula to calculate the PSI.

How do you calculate the thickess of pipe?

By measuring the schedule diameter. That's the distance straight across the inside of the pipe from one side to the other, as opposed to the outside of the pipe to the other.

How can one calculate angular velocity from linear velocity?

To calculate angular velocity from linear velocity, you can use the formula: Angular velocity Linear velocity / Radius. This formula relates the speed of an object moving in a circular path (angular velocity) to its linear speed and the radius of the circle it is moving in.

What is the estimated discharge in acre foot per day of a 4 inch diameter pipe with a velocity of 1 cubic foot per second?

The pipe diameter doesn't matter. If the pipe is discharging a cubic foot per second then it will discharge 86400 cubic feet in a day, because that is the number of seconds in one day. One acre foot is 43560 cubic feet, so the pipe discharges 86400/43560 ~= 1.98 acre feet. On the other hand, if you meant to say the water velocity exiting the pipe is 1 foot per second (not one cubic foot per second), then, assuming you have the average water velocity, you need to figure the flow rate first. The pipe has a radius of 2 in. so its cross sectional area is pi*r^2 = pi*4 ~= 12.57. So a volume of 12.57 in.^2 * 12 in. is discharged per second, which is ~ 150.80 in.^3 or about 0.09 cubic feet. From there it's the same as above. On the other other hand, if your water velocity is not the average over the cross sectional area but instead a point velocity, say at the middle of the stream of water, then you need to figure the average velocity. You'll need a hydraulics book with pipe roughness coefficients for that.

How can one calculate the distance traveled by an object using its velocity and the time it has been in motion?

To calculate the distance traveled by an object, multiply its velocity by the time it has been in motion. This formula is distance velocity x time.

What volume of water is there in a meter of 22mm pipe?

The volume of water in a pipe can be calculated using the formula: volume = area x length. For a 22mm pipe, the area can be calculated using the formula for the area of a circle: πr^2, where r is the radius (11mm). The length of the pipe in this case is 1 meter. By substituting these values into the formula, you can calculate the volume of water in the pipe.

How do you calculate new velocity when speed changes?

That depends: based on what information? One calculation you might do is to add the original velocity with the velocity change (vector addition). However, normally you would proceed the other way: you would have to MEASURE the original velocity and the final velocity, and THEN calculate the difference in velocity.f
