Question

Buoyancy

Answer 1

Don't I need the depth?

Answer 2

V = h*W*depth. I have an equations for part a. I don't get how I am going to solve for h2 when I don't have a volume. I was going to use the ideal gas law PV = mRT to find v, specific volume. Divide PV = mRT by m we get Pv = RT, solve for v. V = mv, however I am not given the mass.

Answer 3

V_a I only know P1 = 100 Kpa and T1 = 293.15K

Answer 4

so which question are we answering?

Answer 5

part a

Answer 6

The parts of the block that are submerged will have a weight associated with it. The part that isn't submerged in a liquid will not have a weight associated with it. I have sum of the forces = 0

Answer 7

Fair + F2 + F3 = mg, where F = row*g*Vdisplaced

Answer 8

Nvm figured it out.

Answer 9

This problem absolutely sucked. For part C I got over 200 ft. I am having a difficult time believing h2 is over 200 ft when pressure is increased to 3000 Kpa. lol
