Hi Can someone help me to derive the spring constant between water molecules based on the bulk modulus of water? It seems simple but i just can't figure it out.
How does spring constant between water molecules in F = - k x relate to the bulk modulus K = - V dp / dV k = spring constant F = force between molecules x = elongation of spring or displacement of molecules relative each other K = bulk modulus of water = 2.2 MPa. It describes the pressure needed to make a relative volume change. 1 % compression requires 22 kPa, 10 % compression requires 220 kPa, etc. V = Volume of the fluid dV = volume change due to pressure dp = pressure change causing volume change This is a general question for all fluids and not only water. It has vortex and rotation applications. I will show you later. David David Jonsson, Sweden, phone callto:+46703000370
