how to calculate pressure for liquid?
for lagrangian fluid simulation, most people uses modified ideal gas law but it's designed for gas, and the coefficients are hard to determine for me because I have no basis to work with. there's also tait's equation that I don't know very much about. so few people use this for SPH simulations even now. if this is the correct equation, why is modified ideal gas equation preferred over this?
