Pipe Flow Calculations Forum

with 2 m/s you will get smaller pipe - which is cheaper, but you have to check pressure drop not to be too high, because if the pressure drop is to high you will have no flow at all.

You need either pressure drop in pipe or velocity. Now, if you want to have 1 m/s velocity than you can calculate diameter for given flow rate and that velocity. http://www.pipeflowcalculations.com/flowrate/index.htm I get 50 mm internal diameter tube. After that you should check pressure drop, to b...

Can you please tell me what mT stands for?

You should know the pressure on the end of pipe and pipe length also

Here is the text that is covering discharge through fittings:

This kind of calculation is not available in the moment, but will be in near future.

For head losses over local resistances you can use following text: http://www.pipeflowcalculations.com/pipeflowtheory/resistance_coefficient_equivalent_length.htm Now, to calculate resistance coefficient for sudden contraction and enlargement, you can use momentum with Bernoulli equations, and it is...

I can suggest you to try to calculate diameter of pipe for maximum of 10m/s. This way you will get minimum pipe size for required flow rate.
To make more precise calculation, pressure drop should be checked. For this, pipe lenghts must be known, as well as local resistances that might occur.

With these values for viscosity you can use equation for mixtures at:

And with mixture viscosity, you can calculate Re number using:

above calculator.

Do you know viscosity of fluid in given positions?

q is for conditions at p1
