Unformatted text preview: ase diagram for water Characteristics of a fluid as compared to a solid? Density, Specific Weight & Specific Gravity Compressibility Density, ρ = mass/unit volume = [M]/[L3]
Density All fluids are at least slightly compressible
Bulk modulus of elasticity, Ev Specific weight , ∆P
change in pressure
∆V change in volume per unit volume Example for water at 10ºC, Ev = 2.1 x ML T 2 =
3 L 2 106 kN/ m2 If pressure increases by 0.1 MPa (~1 atmosphere ),
what is the % change in water volume?
