For Ke= 0.577 in. H2O-min/ft and Ks= 0.00986 in. H2O-min-ft/gr, design a reverse-air baghouseto filter 20,000 cfm of air with 2.5 gr/ft3of flour. Assume a cleaning time of 3.0 minutes anda filtration time of 60 minutes. In your design, specify the number of compartments, themaximum filtering velocity, the cloth area per compartment, and the total number of bagsrequired if each bag is 10 ft long and 1 ft in diameter. Also, specify the maximum pressuredrop that will be experienced during the run.

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
