The viscosity of any fluid increases with an increase in intermolecular attraction forces. In the case of dimethyl ether, methyl alcohol, and glycerol; hydrogen bonding is highest in glycerol then methanol. In dimethyl ether, hydrogen bonding is not there. Thus increasing order of viscosity is dimethyl ether < methyl alcohol < water < glycerol.
