Spray Volume/liquid Displacement

[cdc02254]

I am new to the forum so please go easy on me. I know I may be posting this in the wrong forum but I am a mechanical design engineer so if it doesn't have cogs I am in trouble.

I am working on a project in which i have a pump/perfume bottle type of mechanism, I need to calculate how much liquid is displaced with each pump of the mechanism.

Can someone either help me with this calculation or point me in the correct direction.

Many thanks in advance.

Kind Regards

Brett

Welcome to PF, Brett.
As far as I know, the swept volume of the pump chamber should equal the fluid displacement... barring leakage.

Hello Brett,

Welcome to the forum! I can definitely help you with this calculation. The volume of liquid displaced with each pump of your mechanism is dependent on several factors such as the size of the pump, the pressure applied, and the viscosity of the liquid.

To calculate the volume of liquid displaced, you can use the formula: V = A*h, where V is the volume, A is the cross-sectional area of the pump, and h is the height of the liquid column pushed out by the pump.

To determine the cross-sectional area of the pump, you can measure the diameter of the pump and use the formula: A = π*r^2, where π is the mathematical constant pi and r is the radius of the pump.

Next, you will need to measure the height of the liquid column pushed out by the pump. This can be done by filling the pump with a known volume of liquid and then pumping it out into a measuring cylinder.

Finally, you can use these values to calculate the volume of liquid displaced with each pump.

I hope this helps and good luck with your project!

Best regards,
