Specific volume

  1. Mar 17, 2016 #1
    1. The problem statement, all variables and given/known data
    how to calculate the specific volume in this question ? the author didnt gave the ans though.
    Should i take the volume displaced by the water or volume of the stone ?
    the specific volume is given by the formula v= V / m

    2. Relevant equations


    3. The attempt at a solution

    There's a relationship between specific volume and density you should know:

    what do you mean by " the volume displaced by the water " in the above. if you mean volume of water displaced by the stone- then its equal to volume of the stone as it is dipped in water.

    So , specific volume = volume displaced / (25 / 9.81) or volume displaced / (20 / 9.81) ???

    The specific weight (also known as the unit weight) is the weight per unit volume of a material
    i think you are given the wt. of the material so divide by volume of the displaced water

    which one is correct ? volume displaced / (25 / 9.81) or volume displaced / (20 / 9.81) ???

    the specific volume of a substance is the ratio of the substance's volume to its mass. It is the reciprocal of density and an intrinsic property of matter as well.

    so, it should be volume displaced / (25 / 9.81) ??

    by the above definition it should be
