The data from a settling-column analysis of a dilute suspension of flocculating solids are listed below. Plot the removal percentages at the corresponding coordinates of depth and time. Sketch lines representing 15%, 30%, 45%, 60% and 75% removals through the data. Estimate the overall removal from a settling tank 6.0 ft deep with an overflow rate

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
