How do you calculate air nozzle velocity?
V= q/a
How you calculate the dynamic pressure of fan?
Dynamic pressure of air = 0.5 * density * velocity of air = Pascal Where: Density = kg / cubic meter Velocity of air = m / s
Why does air escaping from the open end of small pipe make a lot more noise than air escaping at the same volume rate from a large pipe?
Because the relative velocity of the air must be greater.
Differentiate between steady flow and pipe unsteady flow?
The velocity is constant in a steady flow pipe while in the unsteady flow the velocity is not constant.
Why do you need to calculate velocity instead of speed?
Speed and Velocity are two different things . Velocity- "the rate at which an object changes its position." Speed- "How fast an object is moving". To calculate speed and velocity, you first need to calculate distance and time. Velocity is considered to be a more logical term
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.
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
Why does the pipe of paper squeezes when air is blown through it?
when air is blown through the paper pipe, the velocity inside the pipe increases and according to Bernoulli's theory the pressure inside the pipe deceases. And the pipe squeezed.
How do you calculate air nozzle velocity?
V= q/a
What is critical velocity in fluid dynamics?
Critical velocity is that The Liquid Air flow in narrow pipe constatly.
How you calculate the dynamic pressure of fan?
Dynamic pressure of air = 0.5 * density * velocity of air = Pascal Where: Density = kg / cubic meter Velocity of air = m / s
Can you calculate pipe diameter if you have pressure head and discharge flow?
Static pressure is .434 X height Example 10 ft x .434 4.34 PSI to prove take 2.31 PSI x 4.34 To find FORCE to need to calculate the diameter of the piping and the height and then the weight of the water inside the pipe
Why does air escaping from the open end of small pipe make a lot more noise than air escaping at the same volume rate from a large pipe?
Because the relative velocity of the air must be greater.
How do you find out water velocity in pipe?
Hello, Velocity in a pipe is the flow divided by the area. If the pipe is full, the area is simply pi*r². Here is a useful calulator for full pipes: http://www.tasonline.co.za/toolbox/pipe/velocity.htm
What is the effect on velocity and pressure if a liquid flows in a convergent pipe?
I think velocity is directly proportionate to its applying pressure.
How can you calculate water velocity from flow rate or diameter of pipe?
if u r talking about presuure drop then it can be easily calculate with the help of relation 4flv*v/2gd in that f is the friction factor which is different for vraious type of flow for that u have to search a good book of fluid mechanics, v is the velocity. length of pipe and d is diameter of pipe
Differentiate between steady flow and pipe unsteady flow?
The velocity is constant in a steady flow pipe while in the unsteady flow the velocity is not constant.
