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.
