Afine aqueous suspension containing 1 lbm of solids per cubic foot of suspension is to be filtered in a constant pressure filter. it is desired to filter at an average rate of 100 gpm, and the filter cake must be removed when it gets 2 in. thick. what filter area is required? data: -ap = 10 psi, p (wet cake) = 85 lbm/ft", k (permeability)=0.118 darcy

r just means there's a number of carbon in teh chain. for example rcooh means that after x number of carbon, the chain ends with cooh.

explanation:

intermolecular forces are the forces between molecules or particles.

there are two kinds of van der waals forces: weak london dispersion forces and stronger dipole-dipole forces.

in molecule of water there are dipole-dipole forces between negatively charged oxygen from one molecule of water and positively charger hydrogen of another molecule of water.

hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom (h), covalently bound to a highly electronegative atom such as flourine (f), oxygen (o) and nitrogen (n) atoms.
