Bulb Pressure System

Click For Summary

To calculate the pressure of a bulb in a system, the formulas p1=Pa+(pgh) and p2=p1+pgh are used. For Bulb A with a specific gravity (SG) of 0.87, the pressure is given as 200 kN/m². Bulb B has a significantly higher SG of 13.6, which implies a different pressure calculation. The discussion emphasizes the importance of following forum guidelines by using a template for clarity and providing a personal attempt at the solution. Accurate calculations depend on understanding the relationship between pressure, specific gravity, and height in the fluid system.

p1=Pa+(pgh)
p2=p1+pgh

Bulb A
SG= 0.87
pressure = 200kn/m^2

Bulb B
SG= 13.6

Hello mohamad, :welcome:

And what is your question ? If you want assistance, the PF guidelines ask that you use the template (so you can reveal what you mean with ##p_1## and ##p_2## etc) and that you post your own attempt at solution.

Thread 'Magnitude of buoyant force in fluids of different densities'

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
