What is the effect of air bubble in transmission line when measuring differential pressure by the using an electronic transducer? Purging is a must before measurement, however if we still have some bubble inside the transmission line or in front of transducer diaphragm, how it may effect to my...

Hi everyone; How I can define the minor loss coefficient(pressure loss) of a filter which has 60nm pore diameter?

Electrical sensor. Let's say transducer.

What is the effect of transmission line while measuring pressure value? I want to learn difference between big and small diameter of measurement line (transmission line).

How I can determine this velocity? Can you give equation or help please?

The exactly question is actually to check whether pressure loses are negligible in unsteady (turbulent, oscilation) conditions.

I actually try to define the pressure loss through diaphragm. When turbulent flow is acting to pressure diaphragm, there is two situation. First of all the diaphragm is always under oscillation. This is the reason why I want to separate the problem into 2 section. First of all when fluid is...

Homework Statement I would like to define pressure loses through transmission line to the transducer. In transmission line I have a reducing union, filter and L pipe. How I can find this differences? In case of frequency my reducing union reduce pipe diameter 6 mm to 3 mm how i can determine...

Homework Statement Is there any difference if I measure static pressure value from the down side of the pipe or up side of the pipe? I am getting an error just small as 300 pascal when I do zero measurement. Here I draw the system also. The diameter of pipe is 10 cm. What could be the possible...

Homework Statement During measurement of flowrate inside a closed circle pipe system, we can have some bubble which can be sticking on orifice plate, or pressure tap, or transmission line. What is the effect of bubbles in these systems? Homework EquationsThe Attempt at a Solution

They are all mixed there ;) maybe try to open an homework page only for mechanical engineering ;)

of averaging of a specific task to get some impression. Or some ways to determine time for quasi steady pressure time with some experiment so on.

Strain gauge
