Ternary Phase Diagram+ Material balance One thousand kg/h of a (50-50 wt%) acetone-in-water solution is to be extracted at 25C in a continuous, countercurrent system with pure 1,1,2-trichloroethane to obtain a raffinate containing 10 wt% acetone. Using the following equilibrium data, determine with an equilateral-triangle diagram: a- the minimum flow rate of solvent; b- the number of stages required for a solvent rate equal to 1.5 times minimum, and composition of each streamleaving each stage. c. Repeat the calculation of (a) and (b) if the solvent used has purity 93wt% (4wr% acetone, 3wt% water impurities) acetone water 1,1,2-trichloroethane Raffinate. Weight Extract.

The dam presented below is 180 m long (in the direction perpendicular to the plane of the cross-section). For the water elevations given on the drawing: a) Construct the flow net (minimum number of equipotential lines should be 10), b) Calculate the rate of seepage for the entire dam, c) Find the total uplift force on the dam (ignore barriers), and d) Estimate the hydraulic gradient at points A, B, and D. Recommended to use a spreadsheet to include all equations for calculations of potentials.

I need the real handdrawing complete it by adding these :  Pneumatic Valves Each linear actuator must be controlled by a directional control valve (DCV) (e.g., 5/2 or 4/2 valve). The bi-directional motor requires a reversible valve to change rotation direction. Pressure Regulators & Air Supply Include two pressure regulators as per the assignment requirement. Show the main compressed air supply line connecting all components. Limit Switches & Safety Features Attach limit switches to each actuator to detect positions. Implement a two-handed push-button safety system to control actuator movement. Connections Between Components Draw air supply lines linking the compressor, valves, and actuators. Clearly label all inputs and outputs for better understanding.
