Is the science of measurement

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

What is the fuid acceleration in vector form for the following velocity field? note i, j, and k are unit vectors. show all of your work.

Asharp-edged orifice is placed in a 10-in-diameter pipe carrying ammonia. if the volume flow rate is 25 gal/min, calculate the deflection of a water manometer (a) if the orifice diameter is 1.0 in and (b) if the orifice diameter is 7.0 in. the ammonia has a specific gravity of 0.83 and a dynamic viscosity of 2.5 x 10-6 lb s/t2
