A column of water has a diameter of 2 m and a depth of 8.6 m. How much pressure is at the bottom of the column? The acceleration of gravity is 9.8 N/kg.
Answer in units of Pa

  • Physics -

    Ignore diameter. It's irrelevant and tries to make it a trick question. And N/kg = m/s/s.
    Just do the pressure in fluids equation, P = ρhg. And water also has a density of 1000 kg/m^3.
    So all you have to do is:
    P = (1000 kg/m^3)(8.6 m)(9.8 m/s/s)
    So your answer is 84,280.
