3. A pump and control valve regulate the flow of the reactor effluent through the heat exchanger. The pump has a discharge pressure described by: q2 (25 psi) 112500 gpm The pressure drop across the heat exchanger is given by: Ppump = (1 q2 (psi) (1) APhx = 1500 gpm Assume that the pressure at the pump inlet are equal. Use: 1 gpm N= and 9s = 1 (psi) 1/2 (a) Find the size (CV) of an equal percentage valve with R= 30, that is fully open at q = 165 gpm. (b) Plot the installed valve characteristic for this valve. Remember: the plot should only have 0
