Hi, I'm currently trying to work out the forces involved in raising a traffic barrier.(adsbygoogle = window.adsbygoogle || []).push({});

It works using hydrolics.

It has a motor that has a speed of 1400 rpm and 1/3 hp. the torque of the motor is 200Nm

the pump is a lobe pump and has a delivery of 1.5 l/min.

The pump will move the hydrolic oil through a hose 50mm^{2}and then into a piston of 1320mm^{2}

I need to work out the force that the pump/ motor is exerting on the fluid. However i am not sure how i can do this only using the mass flow rate.

If anyone can tell me if this can be done/ how to do it would be great. If there is any additional information needed to solve this problem i can probably provide it.,

Thank, Will.
