Hello friends,(adsbygoogle = window.adsbygoogle || []).push({});

I have a problem in Bernoulli equation and Newton Law. I'm going to calculate how much power is needed to lift up an object with weight W.

I'm planning to put the object in a 10 inches diameter. How can I calculate the power needed by the motor to lift up the object? Does the object has friction in it (the object will float)?

The motor will be placed at the bottom of the tube and will give pressure to the object.

I know that there is also an equation like: F= [tex]\frac{P}{A}[/tex]. but how to implement it? I have my assumption for this one that will happen with the object (Attached). Please correct me if I'm wrong.

Any help means a lot.

Thank you :)
