PLEASE HELP!! a 100kmol/h stream that is 97 mol% carbon tetrachloride (CCI 4) molecular weight equal to 154, and 3 mol% carbon disulfide (CS2) molecular weight of 76, is to be recovered from the bottom of the distillation column. The feed to the column is 16% mol carbon disulfide and 84 mol% carbon tetrachloride and 22% of the chloride tetrachloride entering the column in contained in the overhead steam leaving the top column

An engine, weighing 3000 n, is supported on a pedestal mount. it has been observed that the engine induces vibration into the surrounding area through its pedestal at the maximum operating speed. determine the stiffness of the dynamic vibration absorber spring in (n/m) that will reduce the vibration when mounted on the pedestal. the magnitude of the exciting force is 250 n, and the amplitude of motion of the auxiliary mass is to be limited to 2 mm note: in this question type-in right numbers, no decimals, no fractions, no unit. approximate to right number if needed
