Fluid Mechanics: Hydraulic Lift

[verd]

Hi,
I have here a problem that I've been working on, and am not sure if I've gone about it correctly. The method I chose seems too simple, and I was wondering if someone could go over the answer that I've found, and let me know if I'm doing this right.The problem:
The piston of a hydraulic automobile lift is 0.30m in diameter. What gauge pressure, in pascals, is required to lift a car with a mass of 1200kg?

First off, I just calculated it in Pascales, and haven't done the gauge pressure thing yet, but this is the answer that I have come across (Attached)

HM

Hi HM,

Thank you for reaching out with your question about fluid mechanics and hydraulic lift. Based on your calculations and the attached answer, it seems like you are on the right track. However, it would be helpful to see your work and calculations to confirm if you have solved the problem correctly.

In general, when solving problems in fluid mechanics, it is important to first identify the given information, the unknowns, and the relevant equations or principles that can be applied. In this case, the given information includes the diameter of the piston, the mass of the car, and the desired pressure. The unknown in this problem is the gauge pressure. The relevant equation is the equation for pressure in a hydraulic system, which is P=F/A, where P is pressure, F is force, and A is the area.

Based on the given information and the equation, it appears that you have correctly calculated the gauge pressure required to lift the car. However, it would be helpful to show your work and explain your thought process in solving the problem. This will not only help to confirm your answer but also allow for a better understanding of the concept for future problem-solving.

In summary, it seems like you are on the right track with your solution. However, it would be beneficial to show your work and explain your thought process to ensure that you have solved the problem correctly. I hope this helps and good luck with your further studies in fluid mechanics.

Best,
