Given two tanks as shown in the figure below: The levels are maintained as shown in the figure. The valves are used to keep the levels constant as shown: (a) If the valves are 45cm in diameters, what is the force required by the actuator to turn off the water, assuming the water pressure is acting on the face of the valve? (b) What is the valve coefficients and what are the valve sizes? (Table provided in question 1) (C) If the pneumatic actuator pressure line has a maximum pressure of 120psi and 10% of the actuator pressure is required to overcome the spring and tightly close the valve, what is the diameter of the diaphragm in the actuator? Note: Specific gravity for water v=62.4lb/ft2 or 9.81KN/m2 Given two tanks as shown in the figure below: The levels are maintained as shown in the figure.
