    Stroke Volume in pump

    Hi Guys, I am designing a diaphragm pump and I want to calculate stroke volume of a diaphragm pump regarding pressure,I need to have stroke volume for each pressure to calculate pump flow rates. Under diaphragm(rectangular shape)I have a pressure fluid and this fluid pushes the diaphragm up, I...

    formula for Cross flow filtartion and non Newtonian fluid(blood)

    Hi, I am researching on cross flow filtration and the fluid is non Newtonian(Blood)and flow is pulstile too. I have a few questions: 1- For membrane, I am sure that Darcy's Eq. works but I am not sure about feeding line, with considering of pilsatile flow, Can I use Navier stokes formula for...

    [b]Flow delay method[/b]

    Hi, I am looking for a method about delay device in fluid system, the fluid is incompressible. I have oscillatory flow and this flow will be divided to two flow by Y joint, I want to have a delay for one of this pipes, I thought that we can put a chamber for delay but I realized that after...
