P.15.8 Water is pumped through a heat exchanger and control valve. At maximum conditions, the flowrate is 115 gallons per min and the pressure drop across the heat exchanger is 53 psi. The coefficient of the valve CV = 44.8. The fractional opening flow area at normal condition f(x) = 0.5 a. Determine the flowrate at normal and minimum conditions. b. If the fraction movement of the valve stem at normal condition X = 0.16, what is the type of the control valve?
