2. The nominal flow of a liquid through a control valve is 450 gpm. At this flow the frictional pressure drop in the line is 20 psi. The total pressure drop available across the valve and line is 25 psi. Assume the frictional pressure drop in the line is independent of the flow and given the specific gravity of the liquid is 0.85. a. Determine an appropriate valve size with full trim for 100% overcapacity. b. Determine the flow through the valve when it is fully opened. c. Determine the valve gain in gpm/%CO. Assume the valve is fail close and it has linear inherent characteristics.
