This equation helps estimate flow when you know the pipe size and the speed of the fluid. In real systems, it’s often backed up withflow metersor pump performance curves. Quick Reference Table Here’s a chart t
A lawn sprinkler has 20 holes, each of cross-sectional area 2.0x10−2cm2, and is connected to a hose pipe of cross sectional area 2.4cm2. If the speed of water in the hose pipe is 1.5ms−1, the speed of water as it emerges from the holes is A2.25ms−1 B4.5ms−1 C9...
This is air at a constant temp so the density of the air will vary with pressure. The mass flow is constant at any point in the pipe. The mean velocity at a point in the pipe is the mass flow divided by the density, divided by the cross-sectional area of the pipe at that point....
Use the same method to calculate the area of the smaller portion for which you need the percentage. For example, if the smaller portion is 8 inches long and 5 inches wide, 8 x 5 = 40; its area is 40 square inches. Divide the smaller portion's area by the whole piece's area. For...
Strength is directly related to the size (that is, the cross-sectional area) of the muscle. Muscle fibers are capable of developing a maximal force of 3 to 4 kg/cm2 (average = 3.5 kg/cm2) of muscle area. So, let's say that you have increased your muscle size from 100 to 150 ...
Using a calculator, determine the cross-sectional area A of the open channel system you are working with. For instance, if you are trying to find the cross-sectional area of a circular pipe, the equation would be A = \frac{\pi}{4}D^2 ...
How do you find the hydraulic radius? Rh is thehydraulic radius = A/P.P is the wetted perimeter of the cross-sectional area of flow in ft. *You may recall that uniform open channel flow (which is required for use of the Manning equation) occurs for a constant flow rate of water thro...
The flow (Q) is equal to the cross-sectional area of the pipe (A) in a volumetric flow meter, and the velocity of the flowing fluid (v): Q = A * v. The mass flow can be expressed in a mass flow meter as follows: ṁ = Q ∗ρ (where Q is the volumetric flow rate and ...
which you can often determine by measuring the cross-sectional area A of the pipe, duct or riverbed. The second quantity is the velocity v of the air or water at that point. You may have to measure this directly, but in the case of water flowing through a pipe, you ca...
How to find the max height at which a column of water can be supported by the atmosphere? Atmospheric Pressure: The pressure in the water column is directly proportional to the height of the fluid and the density of the fluid. The atmospheric pressure is {eq}...
