Equivalent length of a pipe is a term applied to express the pressure drop generated by valves and fitting in a pipe.
In literature, you usually find ratios of equivalent length to diameter of the pipe. For example, L/D for a fully opened globe valve is 300. This means that, if you have a fully opened globe valve in a pipe and the internal diameter of the pipe is ID=0.05m, then
the equivalent length for this globe valve =300*D=300*(0.05m)=15m.
Equivalent length of 15 meters means that the globe valve generates the same pressure drop as as straight 15-meter long pipe.

Basic mass air flow calculation in pipe?
Mass flow in air can be calculated if you know the pressure drop across the pipe. Then it can be calculated using Darcy's Equation for Pressure,which is: P2-P1 = (4fLv*v)/d*2*g where, P2 & P1 are pressures at two points in pipe, f = friction factor, L= length of pipe, v = velocity of fluid, d = diameter of pipe, g = gravity. from this formula we can calculate the velocity and hence the flow rate.
How Do you calculate the area of pipe?
Start with the maximum flow speed (metres per second) for your liquid, then mutiply by the area of the pipe in square metres, the result is maximum volume flow rate in cubic metres per second.
How many bag of port land cement sand and gravel for 1 meter diameter concrete pipe?
To calculate the materials needed for a 1-meter diameter concrete pipe, you first need to determine the volume of the pipe. The volume of a cylindrical pipe can be calculated using the formula V = πr²h, where r is the radius and h is the height (or length of the pipe). For a 1-meter diameter pipe, the radius is 0.5 meters. If you assume a length of 1 meter, the volume is approximately 0.785 cubic meters. The typical mix for concrete is about 1 part cement, 2 parts sand, and 3 parts gravel by volume; thus, you would need about 1 bag of cement (approximately 50 kg), 0.2 cubic meters of sand, and 0.3 cubic meters of gravel for this volume.

How do you calculate volume of water in a pipe?
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
What will be the surface area of pipe if pipe dia is 6 inch and length is 7.5 meter?
Surface area of the pipe: diameter*pi*length but make sure that the diameter and length are both in meters or inches.
How do you find cubic inches in pipe?
-- Measure the radius of the pipe, in inches. -- Measure the length of the pipe in inches. -- The volume of the pipe is (pi) x (radius)2 x (length) cubic inches

What is the relationship between flow rate and pipe length in a fluid system?
In a fluid system, the flow rate is inversely proportional to the pipe length. This means that as the pipe length increases, the flow rate decreases, and vice versa.
How do you find the inside Area of a pipe?
Measure the length of the pipe and the inner Dia of the pipe. 2 x pi x Radius x length is the inner surface area
