1a / state the formula giving flowrate (qv) in terms of valve flow coefficient, pressure drop across the valve and relative density of fluid. State the units of the variables in the formula.
B/ A valve having a flow coefficient (Kv) of 65 operates with oil of relative density 0.85 and a pressure drop of 1.4 bar across the valve.
Calculate the flowrate of the oil.
A distillation column separates benzene from toluene using a control scheme similar to that shown in Figure (a). Make a practice HAZOP study of the plant section and add any instrumentation that is needed to develop the full P and I diagram.
Let the property P;.. in Eq 5.2-1 be the scalar 1 so that the integral in that equation represents the instantaneous volume V. Show that in this case
The product is neutralized and washed with water to remove salts. The washed product is usually separated by batch distillation, in which unreacted feeds are recovered first, followed by product, and a polymeric waste is left as residue. The batch..
