A20 kg instrument is mounted to four springs in parallel of 800 n/m stiffness each. the mount is subjected to harmonic force of f(t) = 32sin(8t) n. determine the amplitude of steady-state vibration and the frequency

The higher the astm grain size number, the finer the gran is. a)-true b)-false

Derive the correction factor formula for conical nozzle i=-(1+ cosa) and calculate the nozzle angle correction factor for a nozzle whose divergence hal-fangle is 13 (hint: assume that all the mass flow originates at the apex of the cone.

Estimate the change in specific internal energy au and specific enthalpy h from inlet to outlet for ethylene glycol (a liquid) flowing through each of the following devices: (a) a heat exchanger where the glycol temperature increases from 20 °c to 80 °c; (b) a pump operating at about 25 °c and increasing the glycol pressure from 100 kpa to 8 mpa.
