A control valve is used to regulate the flow of sulphuric acid with density of 1830kg/m³. The valve is an equal percentage valve, air to open (ATO) type with a constant pressure drop. The valve position is 0.75 and maximum flow coefficient is 1000 gpm/vpsi. The inlet pressure is 115 psig and the outlet pressure is 70 psig. Rangeability is 50. a) Calculate the flow coefficient for the valve. b) Calculate the valve gain in gpm/%CO assuming that the valve is equal percentage with constant pressure drop. c) Illustrate the transfer function of the valve in b) in term of block diagram if the time constant of valve actuator is 10s.

Back HW#2 QUESTION1/60pts] A fluid of viscosity u flows in the horizontal cylinder (radius R) shown in the figure under a constant pressure gradient dP/dx. The inner core of the cylinder is filled with a porous material. The flow in this porous region is slow and assumed to be a plug-type flow such that the velocity is constant and everywhere the same inside the porous region. Denote this velocity by Uo. The flow in the open (non-porous) region is steady, Newtonian, incompressible and axisymmetric. It will be assumed that only the axial (x) component of the velocity is non-zero. Flow Open flow T&R Porous media flow R N.B. All your answers must be expressed in terms of µ, U₁, a, R and dP/dx. (a) Use the continuity and Navier-Stokes equations to determine the expression of the velocity in the open region. (b) What is the expression of the average velocity in the open region? (c) Is the assumption of a linear velocity profile in the open region acceptable when this region Tuatifi 1:

P.15.4 Glycerine (sp. gr = 1.11) is pumped through a heat exchanger and a control valve. At normal conditions, the flow rate is 200 gallons per min., the pressure drop across the control valve is 5 psi while the total pressure drop is 35 psi, and f(x) for the valve is 0.5. Determine the flow rate and the pressure drop across the control valve at the maximum condition.
