Adhesives distribute loads across the interface, whereas fasteners create areas of localized stresses.
True or False
A continuous column flash system is separating 100 kmol/h of a saturated liquid feed that is 45 mol% methanol and 55 mol% water at 1.0 atm. Operate with L/V = 1.5 and the outlet bottoms at xN = 0.28.
Find the values of FL, FV, y1, and the number of equilibrium stages required.
Find the value of Q used to vaporize FV.
For a normal flash with the same feed and the same V/F, find the values of x and y.
A beer still is being used to separate ethanol from water at 1.0 atm. The saturated liquid feed flow rate is F = 840.0 kmol/h. The feed is 44.0 mol% ethanol. The saturated vapor steam is pure water with ratio of steam flow rate S to feed rate, S/F = 2/3. We desire a bottoms product that is 4.0 mol% ethanol. CMO is valid.
Find the mole fraction of ethanol in the distillate vapor, yD,E.
Find the number of equilibrium stages required.
If the feed is unchanged and the S/F ratio is unchanged, but the number of stages is increased to a very large number, what is the lowest bottoms mole fraction of ethanol that can be obtained?

- The net force exerted on the piston by the exploding fuel-air mixture and friction is 5 kN to the left. A clockwise couple M = 200 N-m acts on the crank AB. The moment of inertia of the crank about A is 0.0003 kg-m2 . The mass of the connecting rod BC is 0.36 kg, and its center of mass is 40 mm from B on the line from B to C. The connecting rod’s moment of inertia about its center of mass is 0.0004 kg-m2 . The mass of the piston is 4.6 kg. The crank AB has a counterclockwise angular velocity of 2000 rpm at the instant shown. Neglect the gravitational forces on the crank, connecting rod, and piston – they still have mass, just don’t include weight on the FBDs. What is the piston’s acceleration?arrow_forwardSolve only no 1 calculations,the one with diagram,I need handwritten expert solutionsarrow_forwardProblem 3 • Compute the coefficient matrix and the right-hand side of the n-parameter Ritz approximation of the equation d du (1+x)· = 0 for 0 < x < 1 dx dx u (0) = 0, u(1) = 1 Use algebraic polynomials for the approximation functions.
